Answer:

Walking speed = 6km/hr or  

60min

6km

Running speed = 8 km/hr or  

60min

8km

Total distance to cover ⇒6km

Total Time taken = 50 min

Let the distance covered while waking = (x)km

running = (6-8)

∴ according to ques :-

6/60

x

8/60

6−x

x=20−18⇒2,

x=2

6−x=4

∴ Now,

(ii) Distance covered while walking ⇒2km
