The speed of the current is 4 miles/hour

Step-by-step explanation:

Let us assume that,

x = speed of the boat,

y = speed of the current.

A motorboat can go 8 miles downstream on a river in 20 minutes or hours.

   --------------------------1

It takes 30 minutes for the boat to go upstream the same 8 miles.

Subtracting equation 1 and 2,

miles/hour
