Bobs typing speed
<u>Solution : </u>
Let the bobs typing speed is x
According to the given question :
Bobs typing speed is x
Bill's typing speed is 19+x
Their combined speed is 97 words per minute.
<u>Solving value x : </u>
x + 19+x = 97
2x + 19 = 97
2x = 97 - 19
2x = 78
x = 78/2
x = 39
Bobs typing speed = 39
Bill's typing speed 39 + 19 = 58
Hence, Bobs speed is 39 words per minute.
