a river 4miles wide is flowing at a rate of 2miles . the minimum time taken by a boat to cross the river with a speed 4 miles per hour in still water is approximately
Added by Anjali C.
Step 1
Given: Velocity of the boat (VB) = 4 miles per hour Velocity of the river (VR) = 2 miles per hour Using the formula VP = sqrt(VR^2 - VB^2): VP = sqrt(2^2 - 4^2) VP = sqrt(4 - 16) VP = sqrt(-12) (ignoring negative value as it represents direction) VP = sqrt(12) VP Show more…
