Question

A city bus drives 3 3/4 of a mile between every stop. It takes the bus a quarter of an hour to travel from one stop to the next. Calculate the unit rate im mph

Answer 1

First, let's get the units cleared:

mph = miles per hour

a quarter of an hour: 0.25 or 1/4 hour

To find the answer, we need to know how long the city bua can travel in an hour.

We can set up an equation to do so:

Let the miles it can drive in an hour be y.

1/4y = 3 3/4

1/4y = 3×4+3/4

1/4y = 15/4

y = 15/4 x 4

y = 15

Therefore, the mph of the city bus is 15 mph.

Hope it helps!
