If a boat is going upstream at 50 MPH and it takes 1.5 hours to go 22 miles, how fast is the current?

Answer by Guest

Lets see whether the river is going against the boat or with it
speed=distance/time
22 miles per 1.5 hour
speed=22/1.5=14.66666 mile per hour

50mph>14.6666666mph
ok it slowed down, so it it going agains the current

boatspeed-currentspeed=realspeed
realspeed=14.666666mph
boatspeed=50mph
50-curretn speed=14.66666666666666
50 both sides
-currentspeed=-35.33333333333333
multiply -1
currentspeed=35.33333333333333mph

the current is 35 and 1/3mph agains the boat
