Question

If a car travels at an average speed of 50km/hr, how much time would it take to complete a trip of 75 kilometers?

Answer 1

Given :

↗ Average speed of car = 50kmph

↗ Distance covered = 75km

To Find :

⏭ Time taken by car to cover the distance.

Concept :

❇ Average speed is defined as the ratio of total distance travelled to the total time taken.

❇ It is a scalar quantity.

❇ It has only magnitude.

❇ It can't be negative or zero.

❇ SI unit : m/s

Calculation :

→ Vav = d / t

→ 50 = 75 / t

→ t = 75 / 50

→ t = 3 / 2

→ t = 1.5 hrs ✔

Answer 2

Answer: 1.5 hr

Explanation:

speed= distance/time

time= distance/speed

time=75/50

      =3/2

      =1.5 hr
