A car is traveling at a steady speed. It travels 2 1/2

Ksivusya [100]

Answer:

It will travel

$33 \frac{1}{4} \: miles$

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

$\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes} = \frac{x}{45 \: minutes} \\ \\ \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} } = \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} } \\ \\ x = 33\frac{3}{4}$
