Question

if Joey drives 222 3/4 miles 3 3/8 hours . if he drives at a constant rate how far will he drive in one hour ?

Answer 1

Start by making the mixed numbers into fractions using that:

`A(b)/(c)=((A\cdot c)+b)/(c)`

According to this:

`222(3)/(4)=((222\cdot4)+3)/(4)=(888+3)/(4)=(891)/(4)`
`3(3)/(8)=((8\cdot3)+3)/(8)=(24+3)/(8)=(27)/(8)`

To find the rate we divide the distance over the time

`((891)/(4))/((27)/(8))=(891\cdot8)/(27\cdot4)=(7128)/(108)=(66mi)/(h)`

The rate idicates that joey drives 66 miles in one hour.
