Two motor boats came out at the same time towards each other. the speed of one of them is 22 km / h, the other is 3 km / h more. The boats met after 4 hours. What is the distance between the marinas?
1. Let’s calculate how many km the first boat covered in 4 hours:
22 × 4 = 88 km.
2. Let’s calculate the speed of the 2nd motor boat:
22 – 3 = 19 km / h.
3. Find the distance the second boat covered in 4 hours:
19 × 4 = 76 km.
4. In order to find the distance between the marinas, add up the distance traveled by both boats:
88 + 76 = 164 km.
Answer: the distance between the marinas is 164 km.
