Question

If you are driving 100 km/h along a straight road and you look to the side for 1.6 s , how far do you travel during this inattentive period

Answer 1

The distance traveled is 44.45 m

Solution:

As per the question:

Average speed,
`\bar{v} = 100\ km/h`

Time, t = 1.6 s

Now, convert the average speed into m/s:

1 km = 1000 m

1 h =
`60* 60 = 3600\ s`

To calculate the distance traveled:

Now,

`100\ km/h = (100* 1000)/(3600) = 27.78\ m/s`

We know that:

Speed,
`\bar{v} = (distance,\ d)/(time,\ t)`

Thus

`d = \bar{v}t`

`d = 27.78* 1.6 = 44.45\ m`
