Question

a tortoise moves a distance of 100 metres in 15 minutes.what is the average speed of tortoise in km/h?

Answer 1

Given:
Distance moved =100m=100/1000=0.1km
time=15min=15/60=0.25hr
Formula:
Average Speed= Total Distance/Total Time                           
                          = 0.1/0.25=0.4 Km/hr
Therefore the average speed of tortoise is 0.4km/hr

Answer 2

Given,

Total distance covered = 100 metres

= 100 / 1000

= 0.1 kilometre

Total time taken = 15 minutes

= 15 / 60

= 0.25 hour

Calculation,

Average Speed = Total distance covered / Total time taken

= 0.1 / 0.25

= 1 * 100 / 25 * 10

= 100 / 250

= 10 / 25

= 0.4 km/hr Ans.

Ans.) The average speed of tortoise in km/hr is 0.4 km/hr.
