If you move 50 meters in 10 seconds, what is your speed (rate)
muminat

Speed is a calculation of distance over time.

So, if we divide our distance, by our time, we will get speed.


So

50 \divide 10 = x\\x = 5

The speed is 5 meters per second

or 5 m/s (Just a different way of expressing the units)

A container of oregano is 17 pounds heavier than a container of peppercorns their total weight is 253 pounds the peppercorns wil
34kurt
Alright, we can turn the word problem at the beginning into an equation.
Let's represent oregano with "o" and peppercorns as "p".
o=p+17
Also, we know that the two added together are 253 pounds.
o+p=253
Since we know that o=p+17, let's substitute it into the second equation.
(p+17)+p=253
2p+17=253
-17       -17
2p=236
p=118
So, we have 118 pounds of peppercorns. (Although it's irrelevant to the second half of the equation, we also know we have 135 pounds of oregano)
Now, let's convert pounds to ounces.
1 pound = 16 ounces.
So, multiply 118 by 16....
118*16=1888
So, you can make 1888 one-ounce bags of peppercorns.
