Mike travels 13 miles per 2 hours on his bike.
LiRa [457]

Answer:

It took Markus half an hour to drive home from work.  He averaged 34 miles per hour.  How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip.  This is a time:

       t  =  1/2

We are given that he averages 34 miles per hour.  This is a rate:

       r  =  34

We are asked how few he has traveled.  This is a distance.  We use the d=rt equation:

       d  =  rt

           =  (34)(1/2)

           =  17

Markus lives 17 miles from work.

Now try one by yourself.  If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

Liz is shipping a package to her friend.the maximum weight of a medium flat-rate box is 20 pounds,including the box which weighs
Murrr4er [49]

Answer:

w+0.375\leq 20 and Liz can ship maximum 19.6 pounds.

Step-by-step explanation:

Let the possible weight of the medium flat-rate box = w pounds.

It is given that there is a box weighing 6 ounces i.e. 0.375 pounds.

Plus, the maximum weight of the package is 20 pounds.

So, we get,

The inequality representing the situation is,

Weight of medium box + 0.375 pounds ≤ Maximum weight of the package

i.e. w+0.375\leq 20

i.e. w\leq 20-0.375

i.e. w\leq 19.6

Thus, Liz can ship maximum 19.6 pounds.
