Answer :-
The average speed of the car is 8.33m/s.
Step-by-step explanation:
To Find :-
- The average speed of car in m/s.
★ Solution
Given that,
- A car travels first 10km in 20mins and another 10km in 30mins.
Let us consider :-
The first 10km in 20mins as s₁ and t₁.
Another 10km in 30mins as s₂ and t₂.
Now,
Total distance covered by the car :-
⇒ (s₁ + s₂)
⇒ (10000 + 10000)m
⇒ 20000m
Total time taken by car :-
⇒ (t₁ + t₂)
⇒ (600 + 1800) seconds
⇒ 2400 seconds
According the question,
We know,
Average speed = Total distance/Total time.
Therefore,
⇒ Total distance/Total time
⇒ 20000/2400
⇒ 8.33m/s
Hence, The average speed of the car is 8.33m/s.
