Question

Suppose you are walking home after school. The distance from your home to school is 5 km. On foot, you can get home in ½ hour. However, if you rode a bike, you could get home in ¼ hour. What is your average speed on foot? What is your average speed on the bike?

Answer 1

Answer:

Average speed on foot = 10kmh-1

Average speed on bike= 20 kmh-1

Explanation:

Average speed on foot = Total distance/Total time taken

                                       =5km/ 0.5h

                                       =10 kmh-1

Average speed on bike = Total distance/ Total time taken

                                       = 5km/ 0.25h

                                       = 20 kmh-1
