While travelling from Nashik to Daman, Harsh drove for 1 hour at a speed of 50 km/h and for the next three hours at 60 km/h. What was his average speed for the whole trip?
Answer & explanation
Correct answer: option 2
Average Speed = \(\frac{Total \; DIstance }{Total \;Time }\)
Total distance = 1 × 50 + 3 × 60 = 50 + 180 = 230 km
Total time = 1 + 3 = 4 hour
Average speed = \(\frac{230 }{4 }\)
= 57.5 km/h
So , Average speed is 57.5 km/h
