Sahil covers a distance of 96 km at the speed of 16 km/h and covers another distance at the speed of 21 km/h in 5 hours. What is his average speed (in km/h)? (Rounded off to 2 decimal places)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 18.27.
Time of first part = 96/16 = 6 hours
Distance of the second part = 21 × 5 = 105 km
Total Distance = 96 + 105 = 201 km
Total Time = 6 + 5 = 11 hours
Average Speed = 201/11 ≈ 18.27 km/h
