Question

A car is driving at 35 kilometers per hour. How far, in meters, does it travel in 2 seconds?metersGive your answer to the nearest meter.

Answer 1

To answer this question we will convert the 35 kilometers per hour to meters per second.

Recall that:

`\begin{gathered} 1km=1000m, \\ 1h=3600s. \end{gathered}`

Therefore:

`35(km)/(h)=35(1000m)/(3600s).`

Simplifying the above result we get:

`35(km)/(h)=35(1)/(3.6)(m)/(s)\approx9.7\bar{2}(m)/(s).`

Therefore, the car travels

`2s*9.7\bar{2}(m)/(s)=19.\bar{4}m\approx19m`

in 2 seconds.

Answer: 19meters.
