The motor boat sailed 75 km at a speed of 15 km / h. How many hours did the boat sail?

The motor boat sailed 75 km at a speed of 15 km / h.

Let’s determine how many hours the boat was on the way.

We apply for the calculation the following formula v = s / t;

In order to find the time, you need to divide the distance by the speed.

We get the formula t = s / v;

Substitute the known values into the formula and calculate the time.

t = s / v = 75 km / (15 km / h) = 75/15 h = 25 * 3 / (5 * 3) h = 25 * 1 / (5 * 1) h = 25/5 h = 5 h …

This means that the boat was on the way for 5 hours.
