I believe it’s 12 minutes since the since the time is unknown, you set it up as x/20+x/30 since you know that they are being added. Filling up the canteen is 1 because you want it full all the way so you find the common denominator and solve for the x which is 12

Emily spent £2400 on holiday in 2017.
LekaFEV [45]

Answer:

£1920

Step-by-step explanation:

The amount she spent in 2016 is 20% less than 2017. 20% less than is the same as 80% of the amount she spent in 2017. So, to find how much she spent in 2016, multiply 2400 by 0.80 (the decimal form of 80%):

2400 * 0.8 = 1920

Emily spent £1920 on holiday in 2016.

I hope this helps :)
