Lauren jogs at a rate of 2 miles every 2/5 hour. at that rate, how long will it take her to job 11 miles?

2 miles every 2/5 hour. 
how long for 11 miles

Make a ratio
2/5  =  x 
2        11

cross multiply
(2/5)(11)=(2)(x)
4.4 = 2x
divide both sides by 2
2.2 = x

It will take her 2.2 hours (or 2 1/5) to jog 11 miles. 

Hope this helps :)

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
