Walt is 3 years older than Ralph Ralph is 4 years older than Henry. If Walt is 48, how old is Henry?
Walt = 48
Ralph =
Henry =

Walt = 48  years

Ralph =  45 years

Henry = 41 years

Step-by-step explanation:

We know that Walt is 3 years older than Ralph so we can write,

Walt = 3 + Ralph        eq. 1

We also know that Ralph is 4 years older than Henry so we can write,

Ralph = 4 + Henry      eq. 2

It is given that Walt's age is 48 years so substitute it into eq. 1

Walt = 3 + Ralph

48 = 3 + Ralph

Ralph = 48 - 3

Ralph = 45 years

Now substitute the age of Ralph into eq. 2

Ralph = 4 + Henry

45 = 4 + Henry

Henry = 45 - 4

Henry = 41 years

Therefore,

Walt = 48  years

Ralph =  45 years

Henry = 41 years

Verification:

Walt = 3 + Ralph        eq. 1

48 = 3 + 45  

48 = 48 satisfied

Ralph = 4 + Henry      eq. 2

45 = 4 + 41

45 = 45 satisfied

its 50 miles away from the starting point
