Harry’s claim is not true because there are 20 ounces in his water bottle and he needs to drink a total of 64 ounces of water. Harry only drank 60 ounces because he filled his water bottle 3 times and 20 times 3 equals 60, there fore he is 4 ounces short of his recommended water intake.

To travel 105 miles, it takes Sue, riding a moped, 3 hours less time than it takes Doreen to travel 64 miles riding a bicycle. S

Volgvan

Let t=time Doreen travels; let r=rate of Doreen

RATE * TIME = DIST.
Sue | r+13 t-3 105
Doreen | r t 64

Now solve the system:
(r+13)(t-3)=105
r*t=64

 $r= \frac{64}{t} 
\\
\\(\frac{64}{t} +13)(t-3)=105 
\\
\\64- \frac{192} {t}+13t-39-105=0
\\
\\13t- \frac{192} {t}-80=0
\\
\\ 13t^2-80t-192=0
\\
\\t_{1,2}= \frac{80\pm \sqrt{(-80)^2-4\times13(-192)} }{2\times13}= \frac{80\pm128}{26} 
\\
\\t=\frac{80+128}{26} =8
\\
\\r=\frac{64}{t} =\frac{64}{8} =8$ 

Doreen: rate = 8 mph, time = 8 hours
Sue: rate = 21 mph, time = 5 hours
