Time
What are some measurements for time?
Seconds, Minutes, Hours, Days, Weeks, Months, Years, etc
What is the symbol/letter for Rate?
What is r?
What is some measurements of distance
What is meters, cemeters, inches, and feet etc.?
Bob has traveled traveled 549 miles in 9 hours. What is the unit rate in miles per hour?
R= d/t
What is 549mi/9h= R (9h)/9h
R=61 mi/h
Isaac is running. He goes 120miles(because he has good legs) in 8 hours. He is traveling at a constant speed. How fast is he traveling(what is the rate)?
What is 15 miles an hour?
What is the symbol/letter for time?
What is t?
Rate can also be called:
What is speed?
What is the symbol/letter for Distance?
What is d?
The distance between two cities is 200 miles. A bus takes 4 hours to cover this distance; calculate the speed of the bus.
What is s=d/t
s=50
Isaac is trying to find Greyson's dad. He runs five hours west at a constant speed going 110 miles an hour. How far away is his dad?
What is 550 miles away?
How can time be used in calculating other variables?
multiple answers possible
What is the equation for Rate/Speed?
what is r = d/t
List an equation where distance is used.
r = d/t
t = d/r
(if you have an equation that is not up there but still uses d then you still get the points)
A car is traveling at 60 miles per hour. They have been traveling for 3 hours until the car reached its destination, what is the distance they traveled?
what is d= r x t
d= 60 x 3h
d=180
Isaac is on a road trip. He drives in a straight line for 350 miles, at a constant speed of 70 miles per hour. How long did he drive for?
List a definition of time.
The measured period of an action being completed; or how long it takes for the said action to be completed. Time can also be associated with speed.(Answer does not have to precisely match description)
list the definition of Rate/Speed
quantity, frequency, or a degree where something is measured per unit, being fast or slow.
list the equation where distance is found
What is d = r × t
2 trains are traveling between Detroit and Los Angeles on the same track. They both leave at the same time and the track is 3,600 km long. Train A is traveling from LA to Detroit and the rate is 80 km per hour and Train B is traveling from Detroit to LA at a rate of 100km per hour. How long would they have to travel?
t=d/r
80t + 100=3,600d
180t=3,600d
t=3,600/180
t=20
Isaac is bungee jumping. He falls at a constant speed of 65 feet per second. He travels for 4 seconds, then bounces back up. How far did he fall?
What is 260 feet?
What is the equation for time?
what is t = d/r
What is the difference between speed and velocity?
Speed calculates how fast an object moves(distance over time), while velocity calculates the displacement and direction of an object over time, or the shortest distance from an object's origin to its final point(displacement over time).
List a definition of Distance
A measurement of length (ex. meters, inches, centimeters, etc).
(The definition does not have to be exact)
A bus left town A for town B. It traveled at a speed of 50 miles per hour, the bus traveled for 50 miles before stopping for 30 minutes due to the road blockage. After the bus started, it increased its speed by 40% to reach its destination on time. If town B is 400 miles from town A, how long did it take the bus to drive to town B?
5h+ 30 minutes = 5h 30 minutes
40% of 50 is 20s
20s+50mi=70s
400mi-50mi=350mi
350mi/70s=5h
Isaac is trying to find his soccer ball. He starts at his house, and runs 30 minutes west, though not in a straight line. When he finds his ball, he ends up two miles west of his house. What is the velocity of Isaac?
What is 1 mph, west?
