Question

It took Ms. Hernandes 4/5 hours

to drive 3/10 of the way to her
uncles house. How many hours
did it take to drive to her unde
house?

Answer 1

2 2/3 hours or 2 hours and 4o minutes

Explanation:

set up a proportion

`(time)/(distance)` =
`(time)/(distance)`

`((4)/(5) )/((3)/(10) )` =
`(h)/(1)`cross multiply and solve for h

`(3)/(10)` h =
`(4)/(5)` Multiply both sides by
`(10)/(3)`

`((10)/(3))`
`(3)/(10)` h =
`((10)/(3))`
`(4)/(5)` Multiply and then divide the top and bottom by 5

h =
`(8)/(3)` o r2
`(2)/(3)`
