One more trip on the Calculus Bus: Given that the bus traveled due east with velocity readings as shown in the table below, estimate how many miles the bus traveled during a $6-$hour trip. $($Here$,$ the velocity of the bus at time $t$ hours is $v(t)mph.$ You may assume that the velocity remained non$-$negative and increasing throughout the trip.$)$

$\backslash$table$[[t,0,0\mathrm{.}75,1\mathrm{.}5,2\mathrm{.}25,3,3\mathrm{.}75,4\mathrm{.}5,5\mathrm{.}25,6],[v(t),0,40,48,55,60,64,67,69,70]]$

Do you think your estimate is too high or too low?
