Answer:
33.75 miles in 45 minutes, 
45 miles in an hour
Step-by-step explanation:
45 minutes: 2 1/3= 7/3 ---> 7/3*3=7, 
                     1 3/4= 7/4 ---> 7/4*3=5.25
car travels 5.25 miles for every 7 minutes,
45/7*5.25= 33.75 miles
1 hour (60 minutes): 
using that the car travels 5.25 miles for every 7 minutes,
60/7*5.25= 45 miles
Hope that makes sense!
