Question

On a school field​ trip, the bus travels 20 miles in 30 minutes. Find the speed of the bus in miles per hour. Use the equation d=​rt, where d is​ distance, r is​ rate, and t is time.

Answer 1

40mph

Explanation:

Using D = rt, the current variables we have are

D = 20 miles

t = 30 minutes

Since the goal is rate, we alter the equation to r = D/t.

In addition, we have to convert minutes into hours so we can

r = (20 / 30)*2/2

r = (40/60)

60 minutes is converted into an hour so the rate r is 40 miles per hour.

r = 40/1
