A boat can go across a lake and return in time T_0 Full Marks at a speed V_1 . On a rough day there is uniform current at speed V_2 to help the onward journey and impede the return -journey. If the time taken to go across and return be T, then T/T_0 :

A boat crosses a lake and returns in time T_0 , at a speed V. On a rough day, there is uniform current al speedy to help the onward journey and impede the return journey. If the time taken to go across and retum on the same day be T. then T/T_0 is

A boat can fo across a lake and retyrb ub tune T_0 at a speed v . On a rough day there is a uniform currednt at speed v_1 to help the onward hourney and impede the return jourmey. If the time taken to go across and return on the same day be (T) then T//T_0 is

A boat can go across a lake of length I and return in time To at a speed yo. On a rough day there is a uniform current moving with a speed y to help onward journey and impede the return journey. If the time taken to go across and return on the rough day is t/(t_0) then the ratio is :

A steam boat goes across a lake and comes back (a) On a quit day when the water is still and (b) On a rough day when there is uniform air current so as to help the journey onward and to impede the journey back. If the speed of the launch on both days was same, in which case it will complete the journey in leaser time.

A steam boat goes across a lake and comes back : (a) on a wuiet day when the water is still and (b) on a rough day when there is a uniform current so as to help the joruney onward and to impede the journey backward ,. If the speed of launch on bothe days same, in which case will it coplete the journey in lesser time?

Rate of current when man go across the width of river in t and t hours.
