Bob has to finish a bunch of orders before going to see a movie starting at 5:30.
He has to bake 3 pies, a dozen doughnuts, 50 cupcakes and 100 cookies.
Each pie takes an hour to cook, A dozen doughnuts take 30 mins, 10 cupcakes take 20 mins and 25 cookies take 10 mins.

If Bob starts cooking at 1:30 will he finish before his movie starts?
Pies = 3 hours
Doughnuts = 30 mins
Cupcakes = 50/10 = 5 x 20 = 100 mins
Cookies = 100/25 = 4 x 10 = 40 mins
First cook all the pies
Batch 1 = 1 hour | Time = 2:30
Then cook 3 batches of cupcakes
Batch 2 = 20 x 3 = 60 mins | Time = 3:30
Cook the last cookies and the doughnuts
Batch 3: 20 x 2 = 40 + 30 = 70 | Time = 4:40
Then finish with the cookies
Batch 4 = 3 x 10 = 30 mins | Time = 5:10
Batch 5 = 1 x 10 = 10mins | Time = 5:20
He will be able to finish all the food before 5:30.
Henry's plane is preparing to take off.
The plane accelerates down the runway for 25 seconds.
At the end of the runway, the plane starts ascending by 250m a second.
After 30 seconds, the plane increases its ascent by 200 more meters.
After 15 secs, the plane levels off.
What's the plane's height now?
250 x 30 = 7500
250+200 = 450
450 x 15 = 6750
7500 + 6750 = 14250
The plane is 14250m or 14.25km high.
A train driver is trying to figure out how many train cars his train can carry. Every car he adds to the train, the train's max speed decreases by 0.1 kph.
The railway runs over a mountain. To make it up the mountain, the train needs to be travelling at a minimum of 30 kph.
If the train's speed without any cars is 50kph, how many cars can the train carry?
Speed = S
Speed Change = 0.1
Original Speed = 50 kph
Minimum Speed = 30 kph
Train Cars = T
50 - T*0.1 ≥ 30
T = 10
50 - 10*0.1 ≥ 30
50 - 1 ≥ 30
49 ≥ 30
T = 100
50 - 100*0.1 ≥ 30
50 - 10 ≥ 30
The train can carry 100 cars.

9 x 9 = 81
8 x 8 = 64
7 x 7 = 49
6 x 6 = 36
5 x 5 = 25
4 x 4 = 16
3 x 3 = 9
2 x 2 = 4

Car B is powered by the sun and can travel at 10m/s but slows down to 2m/s at 20m because of the shade.
Car C is powered by momentum. The car is placed on a large hill 30m behind the start line but can travel at 20m/s.

A new night club will stay open until all of its guests leave. 240 guests enter when the doors open and 240 more come in every hour.
Every hour after that, 20 fewer guests arrive and 40 guests leave.
How long will the club stay open until all the guests leave?
T = 200
P = people
H = hour
A = people that arrive
L = people that leave
T = Total
P + (240 - 20*H) - 40*H = T
H = 1
240 + (240 - 20 x 1) - 40 * 1 =
240 + 220 - 40 = 420
H = 8
240 + (240 - 20 x 8) - 40 * 8 =
240 + 80 - 320 =
320 - 320 = 0
The club is open for 8 hours.
If you multiplied all the numbers on a basic calculator, what would you get?
