Aswimmer wishes to reach directly opposite bank of a river, flowing with velocity 8 m/s. The swimmer can swim 10 m/s in still water. The width of the river is 480 m. Time taken by him to do so:

The displacement-time graph of a moving particle is a inclined straight line. Therefore

A train moving with a constant speed along a straight track takes a bend in a curve with the same speed. Due to this

A particle moves with constant acceleration for 6 seconds after starting from rest. The distances travelled during the consecutive 2 seconds interval are in the ratio
