A motor boat whose speed in still water 9km/hr takes three hours to go 12km dowm stream and come back.Find Speed of the stream.

A motor boat whose speed in still water 18km/hr takes 1 hour more to go 24km up stream than to returns dowm stream to the same spot.Find Speed of the stream.

A motor boat whose speed in still water 15km/hr takes half an hour more to go 18km up stream than to returns dowm stream to the same spot.Find Speed of the stream.

Work Problem related to the form A/(ax+by)+B/(cx+dy)=k A motorboat takes 6 hours to cover 100 km downstream and 30 km back. If the motorboat goes 75 km downstream and returns back to its starting point in 8 hours, find the speed of the motorboat in still water and speed of the stream.

The maximum speed of a train is 90 km/h. It takes 10 hours to cover a distance of 500 km. Find the ratio of its average speed to maximum speed?

A train travels 360 km at a uniform speed.If she had been 5 km/h more,it would have taken 1 hour less for the same journey.Find the speed of the train.

Represent the following situations in the form of quadratic equations:(iv)A train travels a distance of 480 km at a uniform speed.If the speed had ben 8 km/h less,then it would have taken 3 hours more to cover the same distance.We need to find the speed of the train.

Work Problem related to the form A/(ax+by)+B/(cx+dy)=k A boat goes 30 km upstream and 44 km downstream in 10 hours. It can go 40 km upstream and 55 km downstream in 13 hours. Find the speed of the boat in still water and speed of the stream.

Work Problem related to speed, distance and time The ratio of the speed A to B is 2:3 . If A takes 3 hours more then B to cover 30km . Find the speed of A and B.

A train travels a distance 300km at a uniform speed.If the speed of the train is increased by 5km an hour,The journey would have taken to two hours less.Find the original speed of the train.

A train covered a certain distance at a uniform speed.If the train would have been 10 km/h faster,it would have taken 2 hours less than the scheduled time.And if the train were slower by 10 km/h,it would have taken 3 hours more than the scheduled time.Find the distance covered by the train.
