Answer:
24 and 56
Step-by-step explanation:
8*3=24
7*8=56
620, because 125+125+185+185=620, and that would be the perimeter of the rectangle.

Answer:
- k = 45 . . . miles per hour
- k = 1/45 . . . hours per mile
Step-by-step explanation:
One way we can relate distance and time is ...
time = k × distance
Then the value of k (the constant of proportionality) is ...
k = time/distance = 4 hours/(180 miles)
k = (1/45) hours/mile
__
Another way we can relate the variables is ...
distance = k × time
Then the value of k (the constant of proportionality) is ...
k = distance/time = (180 miles)/(4 hours)
k = 45 miles/hour
