Motion is the continuous change in the position of a body with respect to its surroundings. For example, a flying bird, a moving car are in motion. Note: Linear motion, circular motion, periodic motion are some types of motion.

Speed is the distance travelled by a body in unit time. It is mathematically written as Speed = Distance travelled Time taken Note: Speed is a measure of how fast an object is moving. The SI unit of speed is meter per second or m s - 1 .

A bus is moving at a constant speed of 40 km h for 15 minutes . How much distance will it cover

Given, Speed, v = 40 km h - 1 , Time, t = 15 min 60 min = 1 hour 15 min = 15 × 1 60 hour = 1 4 hour We know that, Speed = distance covered time taken Distance, d = v × t d = 40 km h - 1 × 1 4 h = 10 km Distance covered by the bus in 15 minutes is 10 km .
