A river 400 m wide is flowing at a rate of 2.0 m//s .A boat is sailing at a velovity of 10 m/s with respect to the water in a direaction perpendicular to the river .
find the time taken by the boat to reach the opposite bank .

Text Solution

Verified by Experts

Time taken on cros the river ` t= (d )/( v_y) = ( 400 m )/( 10 m//s) = 40 s `
