Question

A car travels a certain distance with a speed of 50 km/h & returns with a speed of 40 km/h. Calculate (i) the average speed & (ii) average velocity of car for the whole journey

Answer 1

HELLO MATE

HERE IS YOUR ANSWER

1 ) AVERAGE SPEED = TOTAL DISTANCE / TOTAL TIME

= 50km + 40km / 2hrs

= 90 km / 2 hrs

= 45 km / hr

2 ) AVERAGE VELOCITY = TOTAL DISPLACEMENT / TOTAL TIME

= 50 km - 40 km / 2 hrs

= 10 km / 2 hrs

= 5 km /hr

THEREFORE , AVERAGE SPEED = 45 km / hr AND AVERAGE VELOCITY = 5 km / hr.
