Question

If sally walked 1/2 mile in 1/4 hour, how fast was she walking measured in miles per hour

Answer 1

2 mile per hour

Explanation:

I use the equation :

`( (1)/(2) )/( (1)/(4) ) = (x)/(1) \\ x = ( (1)/(2) * 1)/( (1)/(4) ) \\ x = ( (1)/(2) )/( (1)/(4) ) \\ x = (1)/(2) * (4)/(2) \\ x = (4)/(2) \\ x = 2 \: mile`

So, she walked 2 mile per hour

Hope it helpful and useful :)
