Answer 2

Let us assume a number of minutes swim by your best friend be X and you be Y.

If you wish to swim 15 minutes more than her, then the equation will be X = Y – 15.

If you swim for 55 minutes, then your friend will swim in 40 minutes.

This means you have to minus your swim minutes from how long your friend swim before i.e. 55 – 15 = 40
