Simultaneously, from two cities, the distance between which is 360 km, two minibuses drove towards each other and met in 2.5 hours. Find the speed of each minibus if the speed of the first one is 8 km / h less than the speed of the second one.

To solve the problem, we first find the speed of convergence of minibuses.

To do this, we divide the initial distance by the meeting time.

We get:

360 / 2.5 = 144 km / h.

We find the speed of convergence of buses without taking into account the difference.

We get:

144 – 8 = 136 km / h.

Find the speed of the second bus.

To do this, divide the resulting rendezvous speed by 2.

136/2 = 68 km / h.

Find the speed of the second minibus.

68 + 8 = 76 km / h.

Answer: The speed of the first minibus is 76 km / h, the speed of the second minibus is 68 km / h.
