Answer:
20000 m³
Step-by-step explanation:
water flowing in river in 1 hour = 2 km = 2000 m
it means
water flowing in river in 60 minutes = 2000 m
water flowing in river in 1 minutes = 2000 = 100
60 3
now we can consider that
length of river = 100 m
3
breadth of river = 40 m
depth of river = 3 m
therefore, volume of water falling in the sea in 1 minutes = length × breadth × height
= (100 × 40 × 3) m³
3
= 4000 m³
therefore, water fall in river in 5 minute = water fall in 1 min × 5
= (4000 × 5) m³
= 20000 m³
HOPE THIS WILL HELP YOU!!
