If the width of something is 5m and the perimeter is 22m, what is the length and area
Nadusha1986 [10]
I assume that this 'something' has a rectangular shape. If its width is 5m, than the length of two sides is 2 * 5 = 10m. Now if the perimeter is 22 square meters, then the lenght of another two sides is 12 / 2 = 6.

12 because 22 (the perimeter) - 10 (lenght of the 2 sides) = 12 (length of another 2 sides).

Eli takes a typing test and types all 240 words in 1 10 hour. He takes the test a second time and types the words in 1 12 hour.
alexandr1967 [171]

Answer:

"faster"

Step-by-step explanation:

Let's put the rates of Eli in WORDS PER MINUTE (the normal measure for typing).

First, we need to convert 1/10th of an hour to minutes. Since there are 60 minutes in an hour, we need to multiply 1/10 with 60. So we have:

1/10 hour = 1/10 * 60 = 6 minutes

Now, converting 1/12th of an hour to minutes in the similar manner, we have:

1/12 hour = 1/12 * 60 = 5 minutes

Hence, first time his wpm (words per minute) is ----- 240/6 = 40 wpm

Also, second time his wpm (words per minute) is ------ 240/5 = 48 wpm

2nd time he was faster (since 48 wpm is greater than 40 wpm).

He was faster on his second attempt.
