Question

A car starts at mile marker 145 on a highway and drives at 55 mi/hrmi/hr in the direction of decreasing marker numbers. What mile marker will the car reach after 2 hours

Answer 1

Answer:

135 mile marker will the car reach after 2 hours.

Explanation:

Speed of the car = 55 mile/hour

Distance covered in 2 hours = d

$Speed=\frac{Distance}{Time}$

$55 mile/hour=\frac{d}{2 hour}$

$d=55 mile/hour\times 2 hour=110 mile$

The direction of the car is in decreasing marker numbers which mienas that car had started from end where 145 mile marker was present.

So, the marker appearing after travelling 2 hours will be:

145 - 110 = 135

135 mile marker will the car reach after 2 hours.
