a car travels 400km in 10 hours. calculate the average speed of the can in km/h and m/s.
Answers
Answer :
Distance travelled by car = 400km
Time of journey = 10h
We have to find average speed of car
◈ What is Speed !
Speed is defined as the ratio of distance travelled to the time taken.
It's a scalar quantity having only magnitude
SI unit : m/s
⇒ Speed = Distance / Time
⇒ Speed = 400/10
⇒ Speed = 40km/h
፨ Conversion (km/h ⟶ m/s) :-
➝ 1km/h = 5/18 m/s
➝ 40km/h = 40×5/18 = 11.11m/s
✭ Speed = 40km/h = 11.11m/s
