First, we look at our needed information. A good idea is to highlight or underline everything we need.
Jaun can type 55 words per minute, so to find how many words he can type in 30 minutes, we multiply 55 by 30.
55×30=1,650.
That means Jaun can type 1,650 words in 30 minutes.
Next, to find how many words Steve can type, we multiply 40 by 30.
40×30=1,200.
Next we subtract 1,650 by 1,200.
1,650-1,200= 450.
The final answer is 450!
Have a nice day!
