Answer:

Alex is 8 -- Horse is 50

Alex is 8-8 = 0 -- Horse is 50-8 = 42 years old

The age of the horse in human years when Alex was born is 12 and this can be determined by using the unitary method.

Given :

  • Eight year old Alex is learning to ride a horse.
  • The trainer says that a horse ages 5 years for every 2 human years.
  • The horse is now 50 years old in human years.

The following steps can be used in order to determine the age of the horse in human years when Alex was born:

Step 1 - The unitary method can be used in order to determine the age of the horse in human years when Alex was born.

Step 2 - According to the given data, if the horse ages 5 years for every 2 human years then 1 human year is equal to:

[tex]=\dfrac{5}{2}[/tex]

= 2.5 years

Step 3 - If 2.5 years is equal to 1 human year then 8 human years is equal to:

[tex]=2.5\times 8[/tex]

= 20 years

Step 4 - The age of the horse when Alex was born is:

= 50 - 20

= 30 years

Step 5 - Now, if 2.5 years is equal to 1 human year then 30 years is equal to:

[tex]=\dfrac{30}{2.5}[/tex]

= 12 human years

The age of the horse in human years when Alex was born is 12.
