Two professional drag racers are speeding down a 1/4mile track. If the lead driver is traveling 1.738 feet for every 1.670 feet that the trailing car travels, and if the trailing car is going 198 miles per hour, how fast in miles per hour is the lead car traveling?

Use proportion:
1.67 ft : 1.738 ft = 198 mph : ?

Ratio of lead driver distance and trailing driver distance = StartFraction 1.716 Over 1.670 EndFraction
Speed of lead car = ratio times speed of trailing car = StartFraction 1.716 Over 1.670 EndFraction times 197 equals 202.4miles per hour
