From two cities, the distance between which is 484 km, two buses left towards each other.

From two cities, the distance between which is 484 km, two buses left towards each other. The first bus left 2 hours earlier and was traveling at a speed of 48 km / h. The buses met 4 hours after the departure of the second bus. What was the speed of the second bus?

The solution of the problem :

1) First, find out the time spent on the way of the first bus. From the problem statement, it is clear that it is two hours more than the time of the second bus:

4 + 2 = 6 hours – the time of the first bus.

2) Find out how long the first bus traveled before meeting the second:

48 * 6 = 288 km – the distance covered by bus number 1.

3) Calculate the route of the bus number 2 to the meeting:

484 – 288 = 196 km – the distance traveled by bus number 2.

4) Find out the speed of the second bus:

196/4 = 49 km / h.

Answer: The speed of the second bus is 49 km / h.
