It would be 7 hours because 35 x 3 is 105, if she is already 105 miles from home then 35 x 7 is 245. 245 + 105 = 350. Candice would be at 350 and Liz would be at 350, so in conclusion the answer is 7 hours. :)
Need to find:
- Perimeter of new square formed?

Solution:
- Side of smaller square = 3cm.
- Side of Bigger square = 9cm

Using formula:
- Perimeter of square = 4 × side

<u>Perimeter of smaller </u><u>square:</u>
⟹ 4 × 3
⟹ 12 cm

<u>Perimeter of Bigger square:</u>
⟹ 4 × 9
⟹ 36cm

Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square
⟹ 36 - 12
⟹ 24 cm

∴ Perimeter of new square formed is 24 cm.
You have to divide both sides by 5 because it states"5t" and you should get "t=20"
