A boat and a motor boat departed from one pier simultaneously in opposite directions. The speed of the boat is 18 km / h, and the speed of the motor boat is 25 km / h. What is the distance between the boat and the motor boat in 4 hours?
1) Let’s find out how far the motor boat and the boat move from each other in 1 hour, if we know that the speed of the motor boat is 25 km / h, and the boat is sailing at a speed of 18 km / h.
25 + 18 = 43 km / h.
2) Let’s determine at what distance the boat and the motor boat will be from each other after 4 hours of travel, if we learned that in 1 hour they move 43 km away from each other.
43 * 4 = 172 km.
Answer: in 4 hours the distance between the motor boat and the boat will be 172 km.
