Answer:t=2.11 hr
Step-by-step explanation:
Given
Aydlett is 2 miles offshore and village is 6 miles down a straight line from the Point on the shore nearest the island
Person can row boat at 2 mph in water and can walk 5 mph in land
Let us suppose Person land the boat at a x miles from Point on the shore
thus time taken by him to reach
Time taken person to reach village by land is
total time
we need the time to be least so differentiate t w.r.t to x
Equating Above term to zero to get minimum time
Substituting x in time equation
The answer is A. a rotation over the x-axis and translation 2 units down
Anyhoot, you can multiply 1.5 by 0.75 to find the time. And you can multiply by 60 to get 67.5 minutes, aka, 1.125 hours
