Question

A car travels from stop A to stop B with a speed of 30 km/h and then returns back to A with

a speed of 50 km/h. Find

(i) displacement of the car.

(ii) distance travelled by the car.

(iii) average speed of the car.

Answer 1

I) total displacement =A-B
II) total distance =A+B
iii) average speed = 2 *50*30/T1+T2

Answer 2

(i)Displacement of the car is 0 ,as it again returns back to the initial point.
(ii) Distance traveled by the car is 80 km, as distance formula is speed× time
(iii) average speed of the car is 40km/ hr as the formula of average speed is( total distance traveled / total time taken)
hope ur doubt is cleared and ur satisfied wid mah answer....☺☺
