that's & nbsp;
If the boat's speed is s mi/hr, then since time = distance/speed,
9090/(s+88) + 9090/(s-88) = 66
The solution seems unreasonable. Check for typos. Like repeated digits. Fix the typos and you will get a nicer answer.
A boat traveled downstream a distance of 9090 mi and then came right back. If the speed of the current was 88 mph and the total trip took 66 hourscomma nbsp, find the average speed of the boat relative to the water.
