Answer:
Step-by-step explanation:
So for this question we have to calculate Speed which is [tex]\frac{Distance}{Time}[/tex]
The speed of the boat in still water is going upstream:
[tex]\frac{240}{60}[/tex] = 4 miles per hour or 4 mph
The speed of the current is going downstream:
[tex]\frac{240}{20}[/tex] = 12 miles per hour or 12 mph
