A person have to go 4 kilometers away from a city. He has to go 2 kilometers by bus and the rest path by walking . If the velocity of the bus be 40 km/hour and the velocity of his walking be 4 km/hour , then find the average velocity of the at person.

A person travels by boat 5 kilometres in 1 hour in still water. The time he requires to travel 40 kilometres against the current is 3 times the time he requires to travel the same distance in favour of the current . Find the velocity of the current .

A man travels a distance in 3 hours with a uniform velocity . If the distance be 2 km more and his velocity be 2 km less per hour then he will take time 1 hour more to travel the new distance . Find the uniform velocity of the man.

A train travels from station A to station B at a constant speed of 40 km. h^(-1) and returns from B to A at 60 km . h^(-1) . Find the average speed and average velocity of the train.

A person travels half of a distance at an average velocity of 24 km. h^(-1) . At what average velocity should he move to cover the second half of the path so that his average velocity for the total path becomes 32 km . h^(-1) ?

Let the velocity of a bicycler in 10 consecutive hours are 17,25,30,32,28,24,20,18,16,10 in kilometers.Find the average velocity.

Express the following statements in the form of simultaneous linear equations and solve them by drawing graphs : (iv) A boat travels 56 km in 4 hours in favour of the current and 48 km in 8 hours against the current. Find the velocity of the boat in steady water and the velocity of the current.

A man swims across the river which flows with a velocity of 3 km/h due east.if the velocity of man relative to water is 4 km/h due north, then How far from his starting point will he reach the opposite bank?
