Question

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

Answer 1

Laurens suv have been travelling 60km/h speed if she can covers the distance of 10 kilometers in 5 minutes.

Step-by-step explanation:

As per the given question,

Distance = 10 km

Time = 5 minutes

Convert minutes into hour.

There are 60 minutes in one hour, hence 5 minutes in hours is written as

`\text { time }=(5)/(60)`

`\text { time }=(1)/(12)`

We know the relationship between distance, speed and time is as follows,

`\text { Distance }(\mathrm{d})=\text { speed }(\mathrm{s}) * \text { time }(\mathrm{t})`

`\text { speed }=\frac{\text {distance}}{\text {time}}`

`\text { speed }=(10)/((1)/(12))`

`\text { Speed }=10 \mathrm{km} * 12 \mathrm{hour}`

Speed = 120km/h

Laurens suv exceeds the limit by = 120 – 60

Thus the speed limit exceeds by 60km/h .
