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

$\frac{x}{70}=\frac{305-x}{65}$

$13x=14\times 305 -14x$

27x=4270

$x=\frac{4270}{27}$

$x=158.148\approx 158.15 miles$

time taken t $=\frac{158.15}{70}=2.259 \approx$ 2.26 hours
