When the boat, whose own speed is 28.4 km / h, went along the river for 2.5 hours, there was still 16.3 km to the pier. The speed of the river was 3.2 km / h. Find the distance between the two marinas.
1) What is the speed of the boat along the river?
28.4 + 3.2 = 31.6 (km / h)
2) How many kilometers did the boat cover in 2.5 hours? To find the distance, you need to multiply the speed by time.
31.6 * 2.5 = 79 (km)
3) What is the distance between the marinas?
79 + 16.3 = 95.3 (km)
Answer. 95.3 km.
