Question

Use your bicycle to go to the market near your home. Come back to your home by using a different path. Measure and note down the time in seconds and distance in meters, from home to market, and from market to home. Calculate your speed for approach and return.​

Answer 1

Answer:

The path from home to market is approximate 900 meters and the time is 3 minutes, that is 180 seconds. Therefore, my speed for approach is v_1=\frac{900\ m}{180\ s}=5\ m/s.v  

1

​  

=  

180 s

900 m

​  

=5 m/s.

The different path from market to home is approximate 850 meters and the time is 175 seconds. Consequently, my speed for return is v_2=\frac{850\ m}{175\ s}\approx 4.86\ m/s.v

​  

=  

175 s

850 m

​  

≈4.86 m/s.
