Answer:
About 4 hours.
Step-by-step explanation:
Let's set up a proportion and cross multiply.
[tex]\frac{28 miles}{1 hour} = \frac{120 miles}{x}[/tex]
Cross multiply.
120 = 28x
Divide by 28 on both sides.
= 4.28571428571
Round this to the nearest whole number, which is just 4. The answer is about 4 hours.
