started boating from a place to another place which is at a distance of 42 km and then again returns to the

starting place. They took 20 hours in all. The time taken by them riding downstream in going 14 km is equal to

the time taken by them riding upstream in going 6 km

(i) Form the pair of linear equations in two variables from this situation.

(ii) Find the speed of the boat in still water and the speed of river.

(iii) The speed of boat in upstream is?

(iv) At what time they will reach the destination, if the speed of boat is increased by 1 km/hr and the speed of
