Question

Water in a canal, 6 metre wide and 1.5 metre deep, is flowing with a speed of 10 km/h. How much area will it irrigate in 30 minutes, if 8 centimeter of standing water is needed?

​Please answer honestly!!!!!

Answer 1

Answer:

Canal is the shape of cuboid where

Breadth = 6 m

Height = 1.5 m

& Speed of canal = 10 km/hr

Speed 10 km/h

h = 1.5 m

b=6m

Length of canal in 1 hour = 10 km

Length of canal in 60 minutes = 10 km

Length of canal in 1 min =

60

x 10 km

30

Length of canal in 30 min = 30/40x 10 = 5km = 5000 m
