Greetings!

The conclusion is:

The return trip will take 18 hours.

Reasoning:

To determine the duration of the return journey, we must calculate the distance from the destination back to the starting point.

The ship travels at 15 miles per hour (mph) over 6 hours, yielding a distance of:

$x=x_o+v*t\\\\x=0+15mph*6hours=90miles$

The distance from the starting point to the destination is 90 miles, and for the return trip, the motor operates at a speed of 5 mph. Thus, computing the time taken gives us:

$Distance=v*t\\\\t=\frac{Distance}{v}=\frac{90miles}{5mph}=18hours$

Consequently, the return trip will take 18 hours to complete.

Have a nice day!
