Answer 1

Answer:

35 km

Step-by-step explanation:

let.....x be required distance.

x/s=t...........

by 1 st condition...

x/25=t+1/15...................................( 4 minutes=1/15 hours)

and by second equation

x/30=t-1/6

from above equations,

x/25 -1/15=x/30 +1/6

so

x=35 km

ans is 35 km
