Answer:
Correct option is
B
6 km
Let the total distance is x km.
Total time=1 hr 24 min=1521min
Tarun covers 32 of the distance at 4 km/hr then time to cover this distance=43s2
Remaining distance=s−3s2=3s1
Tarun covers rest of the distance at 5 km/hr then time to cover rest distance=53s1
∴1521=12s2+15s1
⇒1521=60s14
⇒s=21×6014×15=6km
