Question

If a tap leaks at the rate of 1 L per half minute, how many litres are Lost after 10 minutes?​

Answer 1

20 liters

Explanation:

when working with math problems about the rate that something is happening, it is typically helpful to find the unit rate.

In this case, the unit rate will be how many liters are lost in 1 minute (per unit essentially means per "1" )

we know that 1 liter is lost in 1/2 minute

1/2 minute = 1 liter

×2 ×2 {multiply both sides by 2 to find "1 minute"}

1 minute = 2 liters

So, for every 1 minute, we lose 2 liters

if we have 10 minutes, we can multiply both sides by 10:

1 minute = 2 liters

×10 ×10

10 minutes = 20 liters

So, after 10 minutes, 20 liters are lost

hope this helps!!

Answer 2
