While boarding an aeroplane, a passenger got hurt. The pilot showing promptness and concern, made arrangements to hospitalise the injured and so the plane started late 30 minutes to reach the destination, 1500 km away in time, the pilot increased the speed by 100 km/hr. Find the original speed/hour of the plane.

A plane left 30 minutes late than its scheduled time and in order to reach the destination1500 km away in time, it had to increase the speed by 100 km/h from the usual speed.Find its usual speed.

A plane left 30 minutes late than its scheduled time and in order to reach the destination1500 km away in time, it had to increase the speed by 250 km/h from the usual speed.Find its usual speed.

In a flight of 2800km, an aircraft was slowed down due to bad weather. Its average speed is reduced by 100km/h and time increased by 30 minutes. Find the original duration of the flight.

After covering a distance of 30km with a uniform speed there is some defect in a train engine and therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reaches its destination late by 45 minutes. Had it happened after covering 18 kilometres more, the train would have reached 9 minutes earlier. Find the speed of the train and the distance of journey.

An aeroplane has to go from a point P to another point Q, 1000 km away due north. Wind is blowing due east at a speed of 200 km//h. The air speed of plane is 500 km//h. (a) Find the direction in which the pilot should head the plane to reach the point Q. (b) Find the time taken by the plane to go from P to Q.

An aeroplane has to go from a point A to another point B, 500 km away due 30^@ east of north. Wind is blowing due north at a speed of 20 m//s. The air-speed of the plane is 150 m//s. (a) Find the direction in which the pilot should head the plane to reach the point B. (b) Find the time taken by the plane to go from A to B.

5. After covering a distance of 30 km with a uniform speed there is some defect in train engine and therefore, its speed is reduced to 4/5 of its original speed. Consequently, train reaches its destination late by 45 minutes. Had it happened after covering 18 km more, reached 9 minutes earlier. Find the speed of the train and the distance of covered.

It is 260 km from Patna to Ranchi by air and 320 km by road.an aeroplane takes 30 minutes to go from Patna to Ranchi whereas a delux bus takes 8 hours. a.Find the verge speed of the plane. b.Find the verage speed of the bus. C. Find the average velocity of the plane. d. Find the average velocity of the bus.

The angle of elevation of the top of a building from the foot of the tower is 60^(@) . After a flight of 15 seconds, the angle of elevation changes to 30^(@) . If the aeroplane is flying at a constant height of 1500sqrt3 m find the speed of the plane in km/hr.

A car moving at a speed of 36 km/hr is taking a turn on a circular road of radius 50 m. A small wooden plate is kept on the seat with its plane perpendicular to the radius of the circular road figure. A small bock of mass 100 g is kept on the seat which rests against the plate. The friction coefficient between the block and the plate is mu=0.58. a. Find the normal contact force exerted by the plate on the block. b. The plate is slowly turned so that the angle between the normal to the plate and the radius of the road slowly increases Find the angle at which the block will just start sliding on the plate.
