Answer 1

$75\frac{1}{3}\ miles\ in\ 1\ hour\\\\ x\ miles\ in\ 8\frac{3}{4}\ hours\\\\ making\ cross\ multiplication\\ 75\frac{1}{3}*8\frac{3}{4}=x\\\\ x=\frac{226}{3}*\frac{35}{4}=\frac{7910}{12}=659\frac{1}{6}miles\\\\ Jill\ can\ drive\ 659\frac{1}{6}miles$

Answer 2

Answer:

Distance travelled in  $8 \frac{3}{4}$ hours is 659.17 miles .

Step-by-step explanation:

As given

Jill drives $75 \frac{1}{3}$ miles every hour .

i.e

Jill drives $\frac{226}{3}$ miles every hour .

Now find out the distance travelled in $8 \frac{3}{4}$ hours .

$Distance\ travelled = 8 \frac{3}{4}\times miles\ travelled\ every\ hour$

$Distance\ travelled =\frac{35}{4}\times \frac{226}{3}$

$Distance\ travelled =\frac{7910}{12}$

Distance travelled = 659.17 miles (Approx)

Therefore distance travelled in  $8 \frac{3}{4}$ hours is 659.17 miles .
