Q.10:
A river 3 m deep and 60 m wide is flowing at the rate of 2.4 km/hr. What is the amount of water running into the sea per minute?
Explanation:
Amount of water running per hour into the sea = 3 × 60 × 2.4 × 10^3 cubic m.
Therefore, amount of water per minute running into the sea
= (3 × 60 × 2.4 × 10^3)/60
= 7200 cubic m
MY DOUBT IS WHY IS DIVIDED BY 60 TO CONVERT INTO MINUTES? HE SOULD MULTIPLY BY 60. PLEASE HELP!
