Time
a. Lap 1:
18.03 + 18.00 + 17.99 = 54.02 /3 = 18.01
b. Lap 2:
17.50 + 17.51 + 17.53 = 52.54 / 3 = 17.51
c. Lap 3:
17.98 + 18.00 + 17.99 = 53.97 / 3 = 17.99
Speed
a. Lap 1:
S= D/ T = 75 ft/ 18.01 sec = 4.16 ft/sec
b. Lap 2:
S = D/ T = 75 ft/ 17.51 sec = 4.28 ft/sec
c. Lap 3:
S = D/T = 75 ft / 17.99 sec = 4.17 ft/sec

A car travels at a constant speed of 20 m/s for 2 minutes. The car increases its speed from 20 to 25 m/s during the next minute and then travels at a constant speed of 25 m/s for 2 more minutes. Each student will have to make a graph to show their data, using speed as the y-axis and time as the x-axis. If you want to show the car’s movement over the entire length of time, how much time should your x-axis show?
A.2 minutes
B.4 minutes
C.5 minutes
D.10 minutes
C) 5 minutes
