Step-by-step explanation:
Answer:2.26 hours
Step-by-step explanation:
Given
Rich is driving from Philadelphia to Pittsburgh at 70 mph
and Michelle speed is 65 mph
If Philadelphia and Pittsburgh is 305 miles apart
Let Rich travels x miles in t time
therefore
Michelle travels 305 -x
[tex]\frac{x}{70}=\frac{305-x}{65}[/tex]
[tex]13x=14\times 305 -14x[/tex]
27x=4270
[tex]x=\frac{4270}{27}[/tex]
[tex]x=158.148\approx 158.15 miles[/tex]
time taken t[tex]=\frac{158.15}{70}=2.259 \approx [/tex] 2.26 hours
