The average speed of the entire trip will be calculated as:
Average Speed= (total distance)/(total time)
Total distance covered
50km in the first 3hours
10km is the last hour
Total speed = 50 + 10
= 60KM
Total time = 4 hour
Average speed = 60/4
= 15 KM/Hr

The answer to this is 15 km/h. For the first three hours, they traveled 50 km. For the last hour of their trip, they only traveled 10 km which means that they have traveled for a total of 60 km. If 60 km would be divided into 4, then the answer will be 15. This is why 15 km/h is the answer.

If in case they traveled more for the last hour of the trip, then the answer would surely be different. For example, if they traveled another 50 km, then they would have traveled 20 km/h. Knowing the formula will help you answer questions like this immediately.
