Question

two cars leave town at the same time going in opposite directions. One travels at 70 miles per hour in the other travels at 55 miles per hour. And how many hours will they be 250 miles apart?

Answer 1

Given:

Speed of car A = 70 miles per hour

Speed of car B = 55 miles per hour

Given that they are going in opposite directions, let's find the time it will take them to be 250 miles apart.

Let T represent the number of hours.

Thus, we hae the equation:

70T + 55T = 250

Let's solve for T:

70T + 55T = 250

125T = 250

Divide both sides by 125:

`\begin{gathered} (125T)/(125)=(250)/(125) \\ \\ T=2 \end{gathered}`

Therefore, it will take both cars 2 hours to be 250 miles apart

ANSWER:

2 hours
