Question 328874
Ms. Vu can run 2 5/8 miles in 1 1/4 miles hour.
 At this rate, how many miles can she run in 4 2/5 hour?
:
All these values will translate to exact decimal values(a lot easier to handle)
:
Ms. Vu can run 2.625 miles in 1.25 hours.
 At this rate, how many miles can she run in 4.4 hours?
:
Find her speed; speed = dist/time
s = {{{2.625/1.25}}}
s = 2.1 mph
:
Dist = speed * time
d = 2.1 * 4.4
d = 9.24 mi or, since they like fractions so much, 9{{{24/100}}} = 9{{{6/25}}} mi
:
:
You can also do this as a ratio equation
{{{1.25/4.4}}} = {{{2.625/d}}}
Cross multiply
1.25d = 4.4 * 2.625
1.25d = 11.55
d = {{{11.55/1.25}}}
d = 9.24 mi
