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:

$35\frac{km}{h}=35\frac{1000m}{3600s}.$

Simplifying the above result we get:

$35\frac{km}{h}=35\frac{1}{3.6}\frac{m}{s}\approx9.7\bar{2}\frac{m}{s}.$

Therefore, the car travels

$2s*9.7\bar{2}\frac{m}{s}=19.\bar{4}m\approx19m$

in 2 seconds.

Answer: 19meters.
