Question

Kanta takes 20 minutes to reach her school at an average speed of 6km/hr . If she is required to reach the school in 24 minutes , what should be her speed ?​

Answer 1

Distance = 20×6

= (108/5)km =21.6km

speed = (21.6/24)kmh^-1

= 0.9kmh^-1

Answer 2

Answer:

Time(1) = 20 mins

Speed = 6km/hr × 5/18 = 5m/3s

Speed = Distance/Time

Distance= Speed × Time

Distance= 5m/3s × 20 = 100m/3

Time(2) = 24 mins

Speed = Distance/Time

Speed = 100m/3 × 1/24

Speed = 25m/18s × 18/5 = 5km/hr
