Question

Water flows at a steady rate from a tap. it takes 50 seconds to fill a 5 litre watering can from this tap. the rate at which water flows from the tap is halved. (i) complete. 5 litres = .......................cm3 [1] (ii) 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

5 liters is equal to 5000 cm³. The new flow rate is 50 cm³/s.

Step-by-step explanation:

(i) To convert from liters to cubic centimeters, we can multiply by 1000 since 1 liter is equal to 1000 cubic centimeters. Therefore, 5 liters = 5 x 1000 = 5000 cm³.

(ii) Since the rate at which water flows from the tap is halved, we need to divide the previous flow rate by 2. The previous flow rate was 5 liters in 50 seconds, which is equivalent to 5000 cm³ in 50 seconds. Dividing this by 2 gives us a new flow rate of 2500 cm³ in 50 seconds. To find the flow rate in cubic centimeters per second, we can divide the flow rate by the time taken, which is 50 seconds. Therefore, the updated flow rate is 50 cm³/s.
