The velocity of a plane flying from San Francisco is:

*v*(*t*) = 270where

*t*is measured in hours and*v*(*t*) in miles per hour. Find the average velocity of the plane between the 1st and 4th hours. Homework Help ✎

You are given a velocity function and you want to find average velocity.

Should you use 'average area under the curve' or 'slope of the secant'?
