The present age of Jane is 45 years old and present age of her sister is 9 years old
<em><u>Solution:</u></em>
Let the present age of Jane be "x"
Let the present age of her sister be "y"
<em><u>Jane is 5 times older than her sister</u></em>
present age of Jane = 5(present age of her sister)
x = 5y ---------- eqn 1
<em><u>In 3 years, Jane’s sister will be 1/4 her age</u></em>
Age of sister after 3 years = 3 + y
Age of jane after 3 years = 3 + x
Age of sister after 3 years = 1/4(age of jane after 3 years)

Substitute eqn 1 in above equation

Substitute y = 9 in eqn 1
x = 5(9)
x = 45
Thus present age of Jane is 45 years old and present age of her sister is 9 years old

Answer: 54 gallons</h3>
Work Shown:
(distance)/(gallons used) = (distance)/(gallons used)
(333 miles)/(37 gallons) = (486 miles)/(x gallons)
333/37 = 486/x
333x = 37*486 .... cross multiplication
333x = 17,982
x = (17,982)/333
x = 54 gallons
You need 54 gallons to travel 486 miles.
It would be 4 and 6 i solved it
