Question

A river 3m deep and 40m wide is flowing at the rate of 2km per hour. How much will fall into the sea in a minute?​

Answer 1

Answer:

water flowing in rivers in 1 hours =2 km

water flowing in rivers in 1 house =2000 m

water flowing in rivers in 60 minutes = 2000 m

water flowing in rivers in 1 minutes = 2000 /60 m = 100/ 3

Lengths = 100/3 m

Breadth = 40 m

Heights =3 m

yarr please give points

Answer 2

Answer:

water flowing in river per hour - 2km

we need to convert km in m so it will be 2000m per hour and we need to convert h in to min so 60 min as u know

water flowing in river 1 min -

$\frac{2000}{60}m = \frac{100}{3}$

River is a shape of cuboid

length= 100/3

breadth=40

height=3 m

volume of falling water in one min = vol of cuboid

$l \times b \times h$

$( \frac{100}{3} \times 40 \times 3) {m}^{3} = 4000m {}^{3}$

Answer 3

Answer:

water flowing in river per hour - 2km

we need to convert km in m so it will be 2000m per hour and we need to convert h in to min so 60 min as u know

water flowing in river 1 min -

$l \times b \times h$

$( \frac{100}{3} \times 40 \times 3) {m}^{3} = 4000m {}^{3}$

sorry I didn't understand why it came twice
