Answer:
Number of full size cars = 900
Step-by-step explanation:
The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are there in both ratios , we need to make the number in the ratio for compact cars to be the same.

Multiply by 8 on numerator and denominator


Multiply numerator and denominator by 5.

Ratio of medium, compact and full size are in ratio 56,40,45.
Total number of cars =2820.
(56 + 40 + 45)x = 2820
x = 
x = 20
Number of full size cars =
=900

We wish to know how much faster Grant rows than Arianna.
d=G-A and we want our answer is miles/hour so
d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)
d=10mph-6mph
d=4mph
So Grant rows 4 miles per hour faster than Arianna.
