Answer 1

`75(1)/(3)\ miles\ in\ 1\ hour\\\\ x\ miles\ in\ 8(3)/(4)\ hours\\\\ making\ cross\ multiplication\\ 75(1)/(3)*8(3)/(4)=x\\\\ x=(226)/(3)*(35)/(4)=(7910)/(12)=659(1)/(6)miles\\\\ Jill\ can\ drive\ 659(1)/(6)miles`

Answer 2

Distance travelled in
`8 (3)/(4)` hours is 659.17 miles .

Explanation:

As given

Jill drives
`75 (1)/(3)` miles every hour .

i.e

Jill drives
`(226)/(3)` miles every hour .

Now find out the distance travelled in
`8 (3)/(4)` hours .

`Distance\ travelled = 8 (3)/(4)* miles\ travelled\ every\ hour`

`Distance\ travelled =(35)/(4)* (226)/(3)`

`Distance\ travelled =(7910)/(12)`

Distance travelled = 659.17 miles (Approx)

Therefore distance travelled in
`8 (3)/(4)` hours is 659.17 miles .
