Answer:
x = 2.26 miles from the shore P i.e. point at which boat be landed.
Explanation:
x is the distance from point of landing i.e R and P
So, she cover a distance miles
She rows with a speed of 3 miles per hour.
So, time taken for rowing
She walks a distance = RQ = 14-x
She walks with a speed of 4 miles per hour.
So, time taken by the woman for walking \
Thus, total time taken
For total time to be least, T ' = 0
T '
x = 2.26 miles from the shore P
