Question

If i ran 2/3 of a mile in half an hour how many miles will i run in 3 hours

Answer 1

4 miles

Explanation:

Using the fact you run 2/3 of a mile in half an hour in 1 full hour you run 4/3

multiply that by 3 and you get 12/3 so 4 miles

Answer 2

4 miles

Explanation:

x₁ = 2/3 mile

y₁ = 1/2 hour

x₂ = ?

y₂ = 3 hours

x₁/y₁ = x₂/y₂

`((2)/(3) )/((1)/(2) ) =(x2)/(3)`

`3*(2)/(3) =(1)/(2) x2`
`x2=2/(1)/(2)`

x₂ = 4 miles
