Two buses left two points to meet each other at the same time. The speed of one bus is 45 km / h and the speed

Two buses left two points to meet each other at the same time. The speed of one bus is 45 km / h and the speed of the other bus is 72 km / h. The first bus traveled 135 km before the meeting. Find the distance between points.

1) We know the speed of the first bus and the distance it traveled before meeting the second bus, so we can calculate how long the bus was on the way:

135: 45 = 3 hours.

2) The second bus was also on the way for 3 hours, as the buses left the points at the same time.

3) Determine how many kilometers the second bus traveled to the meeting point:

72 * 3 = 216 km.

4) Adding the distances that the buses traveled before the meeting, we find out the distance between the points:

135 + 216 = 351 km.

Answer: 351 km.
