Bisi lives 5km from school, she walks 1km at 4km/h and travels the rest of the wayby bus at 16km/h. What is the average speed of the whole distance

Answer 1

To calculate the average speed for the whole distance, we need to first find the total time taken for the journey.

Time taken to walk 1km at 4km/h = 1/4 hours
Time taken to travel the rest of the way by bus (4km) at 16km/h = 4/16 hours = 1/4 hours

Total time taken = 1/4 + 1/4 = 1/2 hours

Total distance = 5km

Average speed = Total distance / Total time taken
Average speed = 5 / 1/2
Average speed = 5 * 2 = 10 km/h

Therefore, the average speed of the whole distance is 10 km/h.
