Question

A car is driving at 100 kilometers per hour. How far does it travel in 2 seconds?

Answer 1

Answer:

$\frac{1}{18}\ km$  or  $\frac{500}{9}\ m$

Step-by-step explanation:

Remember that

1 hour=3,600 seconds

so

by using proportion

$\frac{100}{3,600}\frac{km}{sec} =\frac{x}{2}\frac{km}{sec} \\ \\x=2*100/3,600\\ \\x=\frac{1}{18}\ km$

Convert to meters

$(1,000)*(\frac{1}{18})=\frac{500}{9}\ m$
