Question

A tortoise moves a distance of 100m in 15mins. What is the average speed of tortoise in kmmh

Answer 1

total distance traveled = 100m
total time taken= 15 minutes = 15*60 seconds = 900 seconds
so average speed of the tortoise = total distance traveled / total time taken
                                                    = 100/900
                                                    = 1/9 meter second
                                                    = 1/9*18/5 kilometer per hour
                                                    = 0.4 kilometer per hour
HOPE MY ANSWER WILL HELP YOU.

Answer 2

Answer:

Total distance = 100m

total time = 15 minutes

= 15 x 60 secs                                        ( 1 minute = 60 seconds)

= 900 secs

Average speed = total distance / total time

= 100/900 m / s

= 1/9 m / s

= 1/9 x 18/5 km / hr       ( To concert into km/hr, multiply by 18/5 )

 = 0.4 km / hr
