Question

laurens suv was detected exceeding the posted speed limit of 60 kilometers per hour , how many kilometers would she have been traveling over the limit is she had covered a distance of 10 kilometers in 5 minutes?

Answer 1

The distance cover for speed limit of 60 kilometer per hour is 5 km

Explanation:

Given as :

The exceed speed limited of Laurens suv = 60 kmph

The time taken cover the distance of 10 km is 5 min

So, time =
`(5)/(60)` hour

Or, time =
`(1)/(12)` hour

So, the speed =
`(Distance)/(Time)`

I.e speed =
`(10)/((1)/(12))` hour

Or, speed = 120 kmph

∵ For the speed of 120 kmph , the distance cover = 10 km

∴ For the speed of 60 kmph the distance cover=
`(10)/(120)` ×60

I,e For the speed of 60 kmph ,the distance cover =
`(600)/(120)`

or, For the speed of 60 kmph ,the distance cover = 5 km

Hence The distance cover for speed limit of 60 kilometer per hour is 5 km . Answer
