Distance Formula: D = Speed x time

D=%28S%5BC1%5D%2BS%5BC2%5D%29%28t%29
180mi=%2855%2B65%29%28t%29
180=120%28t%29 ----> cross%28180%291.5%2Fcross%28120%29=cross%28120%29t%2Fcross%28120%29
red%28t=1.5hrs%29, Answer

Let us check, by computing the Distance of each cars with the Speed in 1.5 hours
D%5BC1%5D=S%5B1%5Dt=%2855%29%281.5%29=82.5miles

D%5BC2%5D=S%5B2%5Dt=%2865%29%281.5%29=97.5miles

Then,
D%5BC1%5D%2BD%5BC2%5D=180miles
82.5%2B97.5=180
180miles=180miles


Thank you,
