Question

A boat went 75 miles in 2 hours with the current and 4 hours without. What was the boat and current's speed?

Answer 1

d=vt
v=d/t
v(boat)=75mi/4hr=18.75 mi/hr
v(boat)+v(current)=75mi/2hr
18.75mi/hr +v(current)=75mi/2hr
v(current)=75mi/2hr-18.75mi/hr=18.75mi/hr

Answer 2

whats v

Answer 3

velocity

Answer 4

ok

Answer 5

so the speed of the boat is 18.75?

Answer 6

yes the boat and the current travel at the same speed, which is why the time doubles when the current is not flowing

Answer 7

Are you sure you posted the problem correctly? Typically these problems have the boat going with the current and against the current.

The boat went 75 miles in 4 hours without any current. So its speed must be 75/4=18.75
