Question

A girl walk a distance of 2km in 40 minute. Find her speed

Answer 1

Answer:

Explanation:

Average speed = Total distance covered / Time taken

                         =  2 km / 40 min

                         = (2 x 1000) m /(40 x 60) s

                          = 2000/2400 m/s

                          = 0.833 m/s

                       

Answer 2

Answer : speed = distance / time.

distance = 2km

time = 40 min = 0.66 hr

therefore speed = 2 km / 0.66hr

= 3.03 km/hr

= 3km/ hr
