The time required to travel a circular field along its diameter is 30 sec less than the time required to travel it along its circumference by a person. If the speed of the person be 60 m per minute, then find the diameter of the circular field.

The time required by a motor car to travel a cartain distance is 3 hours less if its velocity be increased by 9 kilometres per hour. Again ,if the velocity be decreased by 6 kilometres per hour , then the time required by the car to travel the same distance is 3 hours more. Find the velocity of the car and the certain distance.

The distance between two places is 200 km. The time taken by moter car to travel from one place to another is more by 2 hrs than the time taken by a zeep car.If the speed of the motor car is 5 kms/hr less than the speed of the zeep car, then find the speed of the motor car.

A horse travelled a circular field in 1(1)/(2) minutes at a speed of 66 m per minute. What is the radius of the field ?

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 .

The diagonal of a rectangular field is 15 m and its length is 3 m more than its breadth.Find out the required quadratic equation in one variable

If the area of the curved surface of a right circular cone is sqrt17 times the area of its base, then the ratio of the height and diameter of the base of the cone is

A man running along a circular track at the rate of 10 mile per hour traverses in 36 seconds an arc which subtends 56^@ at the centre. Find the diameter of the circle.

The breadth of a ractangle is 44 m, its length is 2(1)/(2) times of its breadth. Find the diameter of the circle, the circumference of which is equal to the perimeter of the rectangle.

A right circular pot can posses water 120 times the water 120 times the water that a hemispherical basin of diameter 150 cm can passes . If the height of the cylinder be 15 cm , then what will be its diameter ?
