Can you please help me and show work I don’t understand it..

Answer 1

Explanation:

So for this question we have to calculate Speed which is
`(Distance)/(Time)`

The speed of the boat in still water is going upstream:

`(240)/(60)` = 4 miles per hour or 4 mph

The speed of the current is going downstream:

`(240)/(20)` = 12 miles per hour or 12 mph
