Question #5d67b

Answer 1

`5 units`

Explanation:

Let us make a graph of speed`(v)` vs time`(t)`

so,our equation becomes `v` = `|t-3|` (because speed is never negative)

so,our table becomes,
at, `t=0, v=3`
`t=1, v=2`
`t=2, v=1`
`t=3, v=0`
`t=4, v=1`

Now putting the values in the graph, we get a curve.

we know that distance = area under( speed-time) curve

so,area under the curve we obtained is,
`1/2*3*3 + 1/2*1*1` or, `5 units`
