Question #dfe03

Answer 1

displacement is `1920m`

Explanation:

First we use this formula to find displacement
`Deltax=v*t` which `v` is velocity and `t` is time and `Deltax` is displacement
so I infer from your question you two velocity and two time so that's means you have two displacement
So to find total displacement you should find sum of two displacement so that's means `sumDeltax=Deltax_1+Deltax_2`
`Deltax_1=v_1+t_1` and `Deltax_2=v_2+t_2`
`v_1=5` `m`/`s` `,` `v_2=4` `m`/`s` `,` `t_1=4min=4*60s=240s` `,` `t_2=3min=3*60s=180s`
Note: we should use SI units to find SI so that's why I converted minutes to seconds so be careful about this
`Deltax_1=240*5=1200m`
`Deltax_2=180*4=720m`
`sumDeltax=1200+720=1920m`
