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

Step-by-step 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

$rate = \frac{distance}{time}\\\\r = \frac{d}{t}$

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

$r = \frac{d}{t}\\\\r = \frac{12}{0.25}\\\\r = 48 \: mph$

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