Correct Answer - Option 4 : 192 km
Given:
Total time of journey = 7 hrs
Speed of Ashok in first half = 24 km/h
Speed of Ashok in second half = 32 km/h
Formula used:
Distance = speed × time
Calculation:
Let total distance be 2x
Time1 = Distance/speed
⇒ x/24 hrs
Time2 = Distance/speed
⇒ x/32 hrs
Total time = (Time1 + Time2)
⇒ 7 = (x/24 + x/32)
⇒ 7 = (4x + 3x)/96
⇒ 7 = (7x/96)
⇒ x = 96 km
Total distance = 2x
⇒ (2 × 96)
⇒ 192 km
∴ Total distance covered by Ashok is 192 km
