Ashok completes a journey in 7 hours. He travels the first half of the journey at the speed of 24 km/h and the second half of it at the speed of 32 km/h. The total distance of the journey is:
Answer & explanation
Correct answer: option 2
Average Speed = \(\frac{2 × S1 ×S2}{S1 + S2}\)
= \(\frac{2 × 24 ×32}{24 + 32}\)
= \(\frac{2 × 24 ×32}{56}\)
= \(\frac{192}{7}\)
Total time of journey = 7 hours
Distance = Speed × Time
= \(\frac{192}{7}\) × 7 = 192 km
So , Total distance of journey is 192 km
