Question

Jon and Dani live 270 miles apart. One day, they decided to drive toward each other and hang out wherever they met. Jon drove an average of 65 mph, and Dani drove an average of 70 mph. How long did they drive before they met up?

Answer 1

They drive for 2 hours before they met up.

Explanation:

Given,

Jon and Dani live 270 miles apart.

Speed of Jon = 65 m/h

Speed of Dani = 70 m/h

To find the time they drove before they met up.

Formula

Distance = time × velocity

Since, they were coming towards each other,

The relative velocity = (70+65) m /h = 135 m/h

Now,

Required time =
`(270)/(135)` hr = 2 hr

Hence,

They drive for 2 hours before they met up.
