A) 4 h 30 min
B) 4 h 45 min
C) 5 h
D) 6 h
Correct Answer: D
Solution :
Suppose time taken while walking \[=x\,h\] And, time taken on riding \[=y\,h\] \[\therefore \] According to question, \[x+y=4\frac{1}{2}h\] ? (i) Then, \[2y=3\,h\] \[y=1\frac{1}{2}h\] From Eq. (i) \[x=4\frac{1}{2}-1\frac{1}{2}=3\,h\] Time required to walk both ways \[=6\,h\]You need to login to perform this action.
