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:

192 km

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
