We can do this by approximating the area under a curve. But what curve? In this case, imagine that the velocity of the vehicle is a function of time, v(t). We do not have this function, but we do have the values of th function at certain points in time. If we assume the function (the velocity) is constant between these points in time (which is not actually true), we can get an approximation. distance traveled - feet Give another estimate using the velocities at the end of the time periods. distance traveled feet Question Help: Video 20210110 2205M2 ing 20210110 220552 jpgarrow_forwardDanny takes his dog to the local dog park every morning, as well (dog-walking is very popular in this area).
