Answer: 24 and 37
Step-by-step explanation:
Let the numbers be x and y . Also let us pick x as the larger number.
From the first statement :
x + y = 61 ............................ equation 1
From the second statement :
x = y + 13 ............................equation 2
Solving the resulting linear equations by substitution method, substitute x = y + 13 into equation 1, then
x + y = 61 becomes
y + 13 + y = 61
2y + 13 = 61
2y = 48
y = 24
Substitute y = 24 into equation 2 , then
x = y + 3 becomes
x = 24 + 13
x = 37
Therefore the numbers are 24 and 37
Proportional means equal, by the way.
I know that this is a proportional relationship because, if you really look at it, you can see the equality between the three pieces of data. 1/2 = 2/4, and 2/4 mile in 2/3 minute... Divide those two numerators by 2/2 and you get the next data piece. Now, multiply the second data piece by 3/3, and you get the third piece.
Now, look at the numbers I told you to multiply/divide by. They all equal 1. In other words, the only difference between them is the time, the unit rate of the distance (1/4 mile/1/3 min) remains the same.
