Wendy can ride her bike 0.8 miles in 6 minutes how many miles can she ride her bike in 2.5 hours

20 miles

Step-by-step explanation:

Set up a proportion...

0.8 miles is to x miles as 6 mins is to 2.5 hours

*You need to convert 2.5 hours into minutes first, since the first part is in minutes.  There are 60 minutes in an hour, so there are 60(2.5) = 150 minutes in 2.5 hours

0.8/x = 6/150

Now solve for x by cross multiplying...

0.8(150) = 6x

    120 = 6x

       20 = x

She can ride 20 miles in 2.5 hours

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
