on a graph starting at 0 and sloping up to 480 on total # of words typed and 16 time in mins. Hannahs typing ability Kerry can type the same # of words in half the time.
a)what rate does Hannah type?
b)what rate does Kerry type?
c)How many words can Kerry type in 8 mins?
To find the rate at which Hannah types, we need to use the formula rate = total / time. In this case, the total number of words typed by Hannah is 480, and the time taken is 16 minutes.
a) To find Hannah's typing rate, we divide the total number of words typed by the time taken:
Hannah's typing rate = 480 words / 16 minutes = 30 words per minute.
Now, since Kerry can type the same number of words in half the time, we can find Kerry's typing rate.
b) Kerry's typing rate is half of Hannah's typing rate because Kerry takes half the time to type the same number of words:
Kerry's typing rate = 30 words per minute / 2 = 15 words per minute.
c) To find how many words Kerry can type in 8 minutes, we multiply Kerry's typing rate by the time:
Words Kerry can type = Kerry's typing rate * Time = 15 words per minute * 8 minutes = 120 words.
So, Kerry can type 120 words in 8 minutes.
