If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:

Two cyclists,moving with equal speeds of 10 km/hr,are approaching each oher along a straight road.When the distance between them is 20 km a fly starting from cycle,keeps on flying alternatively from one cycle to the other.If the fly has a constant speed of 40 km/hr.Find the total distance travelled by the fly before the cyclists meet is.

A train travels a distance of 480 km at a uniform speed. If the speed had been 8km/h less, then it would have taken 3 hours more to cover the same distance. We need to find the speed of the train.

Represent the following situations in the form of quadratic equations : A train travels a distance of 480 km at a uniform speed. If the speed had been 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.

Two ships A and B are sailing away from a point O along routes such that angle AOB is always 120^(@) . At a certain instance, OA = 8 KM OB = 6km and the ship A is sailing at the rate of 20 km/hr while the ship B sailing at the rate of 30km/hr while the ship B sailing at the rate of 30 km/hr. Then the distance between A and B is changing at the rate (in km/hr)

A car starts from and attains the speed of 1 km/hr nad 2,ms/hr at the end of 1st and 2nd minutes. IF the car moves on straight road, the distance travelled in 2 minutes is

Surya can walk 18/5 km in an hour how much distance can he walk in 2 1/2 hours?

A man walks at a speed of 6 km/hr for 1 km and 8 km/h for the next 1km. What is his average speed of the walk of 2 km?
