Question

Two cars leave a rest stop at the same time and proceed to travel down the highway in the same direction. One travels at an average rate of 49 miles per hour, and the
other at an average rate of 68 miles per hour. How far apart are the two cars after 4.5 hours?

Answer 1

Answer:

The answer is going to be 85.5 miles apart.

Step-by-step explanation:

if the first car is going 49 miles for every hour and the second at 68 we now have our two numbers. then we know its 4.5 hours so our equation goes like this.

(68*4.5)-(49*4.5)=y

We do our rules with pemdas and what not.

we get

306-220.5=y

We subtract and bam

y= 85.5 miles apart.

Hope this helps.
