Question

please help, thank you so much.

the barge travels upstream 75.5 miles to the factory and then back to the warehouse.the barge travels upstream at a rate of 5 miles per hour slower than it travels downstream.the barge total time is 15 hours.what is the rate the barge travels downstream?

Answer 1

let speed upstream=x mi/hr
then downstream speed=x+5 m/hr
distance =75.5 miles
\[\frac{ 75.5 }{ x }+\frac{ 75.5 }{ x+5 }=15\]
calculate x
