An airplane starts from a and flies to b at a constant speed. after reaching b it returns to a at the same speed. there was no wind. assuming there was a wind from a to b of constant magnitude, when will the round trip take more time – when there is a wind or when there is no wind? assume that the wind speed is less than that of the plane.
1. longer round trip time when there is a constant wind.
2. more information is needed.
3. the same time in both cases.
4. longer round trip time when there is no wind.

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
