To find the average speed while walking, we need to divide the distance traveled by the time taken:
Average speed while walking = Distance / Time = 5 km / 25 minutes
To simplify the units, let's convert minutes to hours by dividing by 60:
Average speed while walking = 5 km / (25/60) hours = 5 km / (5/12) hours = 5 km * (12/5) / 1 hour = 12 km/h
Therefore, the average speed while walking is 12 km/h.
Similarly, to find the average speed while bicycling, we use the same formula:
Average speed while bicycling = Distance / Time = 5 km / 10 minutes
Converting minutes to hours:
Average speed while bicycling = 5 km / (10/60) hours = 5 km / (1/6) hours = 5 km * 6 / 1 hour = 30 km/h
Therefore, the average speed while bicycling is 30 km/h.
To find how much faster you travel on your bicycle compared to walking, we can subtract the average walking speed from the average bicycling speed:
Relative speed on bicycle = Average speed while bicycling - Average speed while walking = 30 km/h - 12 km/h
Relative speed on bicycle = 18 km/h
Therefore, you travel 18 km/h faster on your bicycle compared to walking.
Suppose you’re walking home after school the distance from school to your home is 5 km on Foote. You can get home in 25 minutes however if you wrote a bike you could get home in 10 minutes what is your average speed while walking? What is your average speedway, bicycling and how much faster you travel on your bicycle?
