3. 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
destination 200 miles away. letting x represent the
f 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
a. if the car spends 2.5 hours going 35 miles per hour on the trip, how long does it spend going 55
miles per hour?
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
