Question 875053
A boat traveled against the current for 70 miles for the same time it traveled with the current for 95 miles. What was the boat's average speed if the rate of the current was 5 mi/h?
***
let x=average speed of boat
(x+5)=speed of boat with current
(x-5) speed of boat against current
travel time=distance/speed
{{{70/(x-5)=95/(x+5)}}}
70x+350=95x-475
25x=825
x=33
average speed of boat=33 mph
