2. A car is traveling on a small highway and is either going 55 miles per hour or 35 miles
per hour, depending on the speed limits, until it reaches its destination 200 miles
away. Letting x represent the amount of time in hours that the car is going 55 miles
per hour, and y being the time in hours that the car is going 35 miles per hour, an
equation describing the relationship is:
55x + 35y = 200
b. if the car spends 3 hours going 55 miles per hour on the trip, how long does it spend going 35 miles per hour
c. if the car spends no time going 35 miles per hour, how long would the trip take? explain your reasoning
