Question:

If a car travels 360 kilometers in 5 hours, how far will it travel in 9 hours?

A 648
explanation

Given that it took 5 hours to travel 360km, we can set up a ratio equation to figure out how far the car will travel in 9 hours: \(\frac{\mathrm{360} }{\mathrm{5}} = \frac{\mathrm{x} }{\mathrm{9}} \)
\(72=\frac{\mathrm{x} }{\mathrm{9}}\)
\(72 \times 9 = x\)
\(X=648\)
