A car is moving along a straight road with a uniform acceleration. It passes through two points P and Q separated by a distance with velocity `30km//h` and `40 km//h` respectively. The velocity of the car midway between P and Q is

A bus is moving along a straight road with a uniform acceleration. It passes through two points A and B separated by a distance with velocity 30 km/h and 40 kmh respectively. The velocity of the bus midway between A and B is:

A car is moving along a straight road with uniform velocity which is the correct representation

A car is moving on a straight road due north with a uniform speed of 50 km h^-1 when it turns left through 90^@ . If the speed remains unchanged after turning, the change in the velocity of the car in the turning process is

Two cars start moving from the junction point of two perpendicular roads with velocity 30 km/h and 40 km/h. The rate at which thay are separating is

A car travels 1/3 of the distance on a straight road with a velocity of 10 km/h, next one-third with a velocity of 20 km/h and the last one-third with a velocity of 60 km/h. Then the average velocity of the car (in km/h) during the whole journey is

A car starting from rest and moving along a straight path with uniform acceleration covers distances p and q in the first two successive equal intervals of time. Find the ratio of p to q.
