Read Solution (Total 2)
-
- (b) 20km
If the distance=x, then
(x/16)-(1/12)=(x/20)+(1/6)
On solving, x=20

- In this problem distance is same..
d = 16(x+1/12)(1/12 hr =5 mins) --------> I
d = 20(x-1/6) (1/6 hr = 10 mins) --------> II
equating I and II equations we get,
x=7/6
so d = 16(7/6 + 1/12) = 20 Km - 10 years agoHelpfull: Yes(0) No(0)
