A tortoise moves a distance of 100m in 15min. What is its average speed in km/hr?
-Added by Himanshi Verma Science » Force And Laws Of Motion
Answer:
Given: Tortoise moves 100 meters in 15 minutes.
Therefore, Average Speed = 100 meters /15 minutes
(as Speed = Distance/time)
= 0.10 Km/ 0.25 hours
(as 1 Km
= 1000 m and 1 hour = 60 min)
= 0.4 Km/hour
Answer – The average speed of tortoise is 0.4 Km/hour
