2.0 40
3.5. 70
4.0 80
5.0 100

2 hours=40

so 1 hour=20

if we use that:

3.5x20=70 as stated

4x20=80 as stated

5x20=100 as stated

so there is a proportional relationshi.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
