A boat sailed from the pier at a speed of 64 km / h. A motor ship immediately sailed behind him at a speed of 26 km / h. How long will the distance between them be 76 km?

To solve this problem, you first need to determine the speed of the boat’s lead over the motor ship.
To do this, subtract the speed of the motor ship from the speed of the boat.
Thus, when this condition is met, we will get.

64-26 = 3 km / h

Now that we know the speed of the boat’s advance over the motor ship, in order to determine the period of time over which a distance of 76 kilometers will arise between them, this distance should be divided by the speed of the advance.

76/38 = 2 hours.

Answer. In 2 hours there will be a distance of 76 kilometers between the boat and the motor ship.
