Question

On a school field​ trip, the bus travels 12 miles in 15 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

Given Information:

Distance = d = 12 miles

Time = t = 15 minutes

Required Information:

Speed of the bus = r = ?

Answer:

Speed of the bus = r = 48 mph

Explanation:

We are given that a bus has traveled a distance of 12 miles in a time period of 15 minutes.

We are required to find the rate or speed at which the bus is traveling.

The relation is given by

`rate = (distance)/(time)\\\\r = (d)/(t)`

Where r is the rate or speed, d is the distance and t is the time.

First let us convert time from minutes to hours

as we know 1 hour has 60 minutes,

15/60 = 0.25 hour

Now we will get the speed of the bus in miles per hour

`r = (d)/(t)\\\\r = (12)/(0.25)\\\\r = 48 \: mph`

Therefore, the speed of the bus is 48 miles per hour.
