Let the speed of the current be x kmhr.
A boat runs at 22 km. Upstream it subtracts from the boat speed. Q 4 - The speed of the boat in still water is 15 kmhr. Upstream speed x y kmhr.
Speed against the current 93 kmhr 3 kmhr. Since it goes 6 km upstream and comes back in 33 minutes we have 6x2 6x-2 3360 11x² - 240x - 44 0 11x² - 242x 2x - 44 0 x - 2211x 2 0 x 22. Cox drives her speed boat 22 km at 45 kmhr.
What is the speed of the boat in still water. Or 6u 2v 1. Therefore the required speed 22 kmh.
10 x 2 10 x 2 55 60. Put in the above equation we get 24u 16v 6. Let frac1xy u and frac1x-y v.
Let speed of the boat in still water x kmhr and. Find out the speed of the boat. 9-x 3 x 9 - 3 6 kmhr.
Description for Correct answer. Find the speed of the boat in still water. Downstream speed x y kmhr.
