river 10 meters deep and 100 meters wide is flowing at themany cubic m

1.	river 10 meters deep and 100 meters wide is flowing at themany cubic metre of water runs into the sea per second.4. Arate of 4.5 km per hour. Find how
Answer» Area of cross section of river = 10×100 =1000sqm Volume of water flow in 1 hour = Area of cross section ×Speed of water flow V=1000× 4.5 km/h V= 1000 ×4.5 ×5/18 m/sec V=1250 m^3 1m ^3 =1000 liter 1250 m^3 = 1000×1250= 1250000 liter in 1 sec

Answer»

Area of cross section of river = 10×100 =1000sqm

Volume of water flow in 1 hour = Area of cross section ×Speed of water flow

V=1000× 4.5 km/h

V= 1000 ×4.5 ×5/18 m/sec

V=1250 m^3

1m ^3 =1000 liter

1250 m^3 = 1000×1250= 1250000 liter in 1 sec
