Question

water flows at a steady rate from a tap it takes 40 seconds to fill a 4 litre watering can from the tap.The rate at which water flows is halved.
4litre=4000cm³
Find the rate at which the water is now flowing from the tap.Give your answer in cubic centimetres per second (cm³/s)

Answer 1

Answer:

2000 cm cube or 2 litres

Step-by-step explanation:

since the rate is halved

therefore, 4000/2 cm cube

= 2000 cm cube

= 2 litres ( since, 1 litre = 1000 cm cube)

Answer 2

Water is flowing 50 cm³/sec.

Step-by-step explanation:

4 liters watering can takes time to fill = 40 seconds

If tap flow is halved,

The time taken to fill 4 liters watering can = 40 × 2

                                                                     = 80 sec.

Given, 4 liter = 4000 cm³

in 80 seconds water is flowing = 4000 cm³

in 1 second water is flowing = $\frac{4000}{80}$

                                              = 50 cm³

Water is flowing 50 cm³/sec.
