I think I would first convert it to hours to solve it and then back to minutes at the end. Super strange it’s been asked for in minutes.

So to convert 20 minutes into hours, you need to multiply by 3.

This means you need to do the same to the other side, cause if they’ve travelled 2.5 miles in 20 minutes, they’d travel 3 times that in an hour.

So this is 7.5m/ph

But then they want it in minutes, so I suppose 7.5/60?

So 0.125m/pm?

$\frac{12}{75} = \frac{4\times 3}{25\times 3} = \frac{4}{25}= \frac{4\times 4}{25\times 4} = \frac{16}{100} =\boxed {0.16}$
