Question

Water is being pumped into a water tank of dimensions 10m×7.5 m× 4m at the rate of 400 l per minute. What is the time taken to fill the the tank completely?

Answer 1

Dear Student,

◆ Answer -

Time taken = 12 hours 30 min

● Explanation -

Capacity of the water tank is -

Capacity of tank = 10 × 7.5 × 4

Capacity of tank = 300 m^3

Capacity of tank = 300000 L

Time taken to fill the tank completely is -

Time taken = 300000 / 400

Time taken = 750 min

Time taken = 12 hours 30 min

Hence, 12 hrs 30 min are required to fill the tank.

Thanks dear. Hope this helps you..

Answer 2

Given : Water is being pumped into a water tank of dimensions 10m × 7.5m × 4m at the rate of 400L per minute.

To find : What is the time taken to fill the the tank completely?

Solution :

• We have to find the capacity of the water tank by finally multiplying all the given values.

→ 10 × 7.5 × 4

→ 300 m³

We have to convert meter cube into litre :

→ 300 × 1000

→ 300000 L

Finding the time taken :

→ 300000/400

→ 750 min

We have to convert 750 min into hour :

→ 750/60

→ 12.5 hours

Therefore, 12.5 hours is the required time taken to fill the tank completely.
