## anonymous one year ago the velocity graph of a car accelerating from rest to a speed of 120 km/h over a period of 30 seconds. estimate the distance traveled during this period

Given a speed and time graph the distance will be the area under the graph

how do i that with left riemann i got a big number that didnt look right

4. anonymous

Can you show what you tried

$v=dx/dt \rightarrow dx=v.dt \rightarrow x=\int\limits_{0}^{30}v.dt$ and you shoude convert km/h into m/s 1km/h ==> (1/3.6)m/s
