Question

A bus travels 36 miles in 45 minutes.
What is the number of miles the bus travels in 60
minutes at this rate?

Answer 1

This way seems to make a lot more sense to me:

Solve for X.

 

(45 minutes)/(60 minutes) = (36 miles)/X

 

Multipy both sides by X/1.

 

(45 minutes)/(60 minutes) * X = (36 miles)

 

Simplify.

 

0.75 * X = (36 miles)

 

Divide both sides by 0.75.

 

X = (36 miles)/.75

 

X = 48 miles

 

So, the answer is the bus travels 48 miles in 60 minutes at that constant rate.

Answer 2

distance = rate x time

 

rate = (36 miles)/(45 minutes) = 0.8 miles/minute

 

distance = (0.8 miles/minute)(60 minutes) = 48 miles
