Question

If a car is traveling at a speed of 28.0 m/s, is it exceeding the speed limit of 55.0 mi/hr?

Answer 1

Answer:

Yes, the car exceeds the speed limit.

Explanation:

The car is travelling at a speed of 28 m/s.

So, in 1 hr or 3600 seconds, the car travels = 28 * 3600 = 100800 meters

We know, 1 mile = 1609.34 meters

Therefore,  

In 1 hr the car would travel = 100800 / 1609.34 = 62.63 miles

The speed limit is given = 55 miles/hr

Thus, we can clearly see that the car is travelling at a speed of 62.63 miles per hour which exceeds the given speed limit of 55 miles/hr.

Answer 2

Answer:

Explanation

speed = 28m/s

time = 28 * 3600 = 100800s

1 hour car travel = 100800/1609 =  62.63 miles

Yes
