Respuesta :
we have paul and jennifer typing speed as 60 words per minute and 80 words per minute.
here we have to identify how do we compare both of these quantities
we need to use ratios.let assume that paul typing speed is a and jennifer typing speed is b
so the ratio is a:b=a/b.
60:80=60/80=3:4.
WE can see :
speed of paul' speed = 60 words per minute
speed of jennifer = 80 word per minute
as jennifer is typing more words than paul we can say that jennifer's spped is greater than paul's sped .
Let us now compare them
we find the difference of their speed
speed of Jennifer - speed of Paul
80 - 60 = 20 word
so we can say Jennifer is 20 word per minute faster than Paul .
