Two cyclists are riding towards each other. The speed of the first of them is 12 km / h, and the speed of the other is 3 km / h more. Now the distance between them is 189 km. How far apart will they be in 3 hours?
Find the speed of the second cyclist.
12 + 3 = 15 km / h.
Let’s find the speed of convergence of cyclists.
12 + 15 = 27km / h.
Let’s find the distance that they will cover in 3 hours.
27 3 = 81 km.
Let’s find out at what distance they will be from each other in 3 hours.
189 – 81 = 108 km.
Answer: In 3 hours the cyclists will be 108 km apart.
