Question

1. An airplane moves at a constant speed of 120 miles per hour for 3 hours. How many miles does it go?

2. A train moves at a constant speed and travels 6 miles in 4 minutes. What is its speed in miles per minute?

3. A car moves at a constant speed of 50 miles per hour. How many hours does it take the care to go 200 miles?

Answer 1

1. 360 miles

2. 1.5m/m

3. 4 hours

Explanation:

1. d (distance) = v (speed) x t (time)

d = 120 x 3

d = 360

2. v = d/t

v = 6/4

v = 1.5

3. t = d/v

t = 200/50

t = 4
