Answer

$\frac{68}{29}$ hours

Work Step by Step

Subtracting tells us the distance between the two cities. 335−199=136. We can solve this problem using the formula distance=rate*time. The distance is 136 miles and the rate is 58 mph. Substituting these numbers into the formula gives $136=58t$. Divide both sides by 58 and simplify to get the answer in hours, $t=\frac{68}{29}$.
