Calculate total distance?

vladimir2022 [97]

Simply find the area under the velocity curve. Over the first 3 second interval, the area is that of a trapezoid with bases 2 and 5, so that area/distance traveled is $\left(\dfrac{2+5}2\dfrac{\rm m}{\rm s}\right)\cdot(3\,\mathrm s)=\dfrac{21}2\,\mathrm m$ . For the last 4 seconds, the area/distance is $\left(5\dfrac{\rm m}{\rm s}\right)(4\,\mathrm s)=20\,\mathrm m$ .

Then the total distance traveled is

$\dfrac{21}2\,\mathrm m+20\,\mathrm m=\dfrac{61}2\,\mathrm m=30.5\,\mathrm m$
