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.

Z varies directly as x and inversely as y.
natta225 [31]

Answer:

y = 6.

Step-by-step explanation:

z = kx/y

9 = k*24/8

24k = 72

k = 3.

So z = 3x/y

When x = 10 and z = 5

5 = 3*10/y

5y = 30

y = 6.
