Dividing the given formula by the rate we get:
[tex]\begin{gathered} \frac{\text{Distance}}{rate}=\frac{rate\cdot time}{rate}, \\ \frac{\text{Distance}}{\text{rate}}=\text{time.} \end{gathered}[/tex]Substituting Distance=120mile and rate=60miles/h we get:
[tex]\text{time}=\frac{120mi}{60\frac{mi}{h}}=\frac{120h}{60}=2h[/tex]Answer: 2h.
