Question

a tortoise moves a distance of 90 meters in 18 minutes.what is the average speed of tortoise in km/h

Answer 1

distance = 90 m = 0.090 Km
time = 18 min. = 18/60 = 0.3 hr

then average speed = distance / time = 0.09 / 0.3 = 0.3 Km/hr

Answer 2

Average speed = Total distance / Time
= (90 m × 10^-3 km / m) / (18 min × 1 hour/(60 min))
= 0.3 kmph

Average speed of tortoise is 0.3 kmph
