a car that traveled 183 miles in 3 hours
a car that traveled 236 miles in 4 hours
a car that traveled 290 miles in 5 hours
a car that traveled 342 miles in 6 hours

Explanation:

Step1: Calculate speed of first car

Speed = $\frac{183}{3}=61$ mph

Step2: Calculate speed of second car

Speed = $\frac{236}{4}=59$ mph

Step3: Calculate speed of third car

Speed = $\frac{290}{5}=58$ mph

Step4: Calculate speed of fourth car

Speed = $\frac{342}{6}=57$ mph

Answer:

A car that traveled 183 miles in 3 hours
