An car moves through 20 m in 3 minutes and the next 50 km at a speed of 100 km/h. What is the approximate average speed of the car?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 25.26 m/s.
Calculations:
Total distance = 20 m + 50000 m = 50020 m
Time taken = (3 + 30) × 60 = 33 × 60 s
Required average speed = 50020/(33 × 60)
= 25.26 m/s
