The boat moves at a speed of 30 km / h. What path will he cover in 3 hours?

Given:
v = 30 kilometers / hour – boat speed;
t = 3 hours – time interval.
It is required to determine L (kilometer) – which way the boat will go during the time interval t.
Since it is not specified in the problem statement, we assume that the boat moves uniformly (that is, at a constant speed). Then, to determine the distance traveled, you must use the following formula:
v = L / t, from here we find that:
L = v * t = 30 * 3 = 90 kilometers.
Answer: in 3 hours the boat will cover a distance of 90 kilometers.
