A car is driving at 100 kilometers per hour. How far does it travel in 2 seconds?
Alisiya [41]

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
