 Question 47820: a motorboat travels 60 kms upstream in 10 hrs if it returns in 8 hrs. . Find th rate of the current and the boat rates are constant during the trip.Answer by venugopalramana(3286)   (Show Source): You can put this solution on YOUR website!a motorboat travels 60 kms upstream in 10 hrs if it returns in 8 hrs. . Find th rate of the current and the boat rates are constant during the trip. LET SPEED OF BOAT IN STILL WATER=B SPEED OF WATER=W UP STREAM SPEED =B-W T=10 HRS....D=60 KM 10(B-W)=60 B-W=6................I DOWN STREAM SPEED = B+W T=8 HRS.....D=60 KM 8(B+W)=60 B+W=60/8=7.5.................II EQN.I+EQN.II 2B=13.5 B=6.75 KMPH W=7.5-6.75=0.75 KMPH
