Question

If you are driving 85 km/h along a straight road and you look to the side for 1.9 s , how far do you travel during this inattentive period?

Answer 1

By definition we have that the distance traveled is equal to:

`d = v * t`

Where,

v: speed

t: time

On the other hand, we have the following unit conversion:

`1 hour = 3600 seconds`

Therefore, substituting values we have:

`d = (85(Km)/(h))*((1.9s)((1)/(3600)(h)/(s)))`

`d = 0.045Km`

Answer:

during this inattentive period you travel:

`d = 0.045Km`

Answer 2

Speed of a vehicle = 85km/hr

We have to calculate the distance traveled in 1.9 second.

Since the speed is given in km/hr, so we will convert the speed into m/s.

We have to multiply the given speed by
`(5)/(18)`.

Therefore, speed = 85km/hr =
`85 * (5)/(18)`

= 23.6 m/s

Since, Distance = Speed
`*` time

Distance =
`23.6 * 1.9`

= 44.8 meters.

So, he traveled for 44.8 meters in 1.9 seconds.
