color(green)(1875) words in 50 minutes

Explanation:

Let x be the number of words Jasper can type in 50 minutes.

This is a basic ratio type of question. We assume that the ratio of words to minutes remains constant.

Therefore
color(white)("XXX")(1125" words")/(30 " minutes") = (x " words")/(50" minutes")

This can be rearranged as
color(white)("XXX")x" words" = (1125 " words"xx 50 cancel(" minutes"))/(30 cancel(" minutes"))

color(white)("XXXXXXXX")= (color(red)(cancelcolor(black)(1125)^color(black)(375)) " words"xx 5color(blue)(cancelcolor(black)(0)))/(color(red)(cancelcolor(black)(3)color(blue)(cancelcolor(black)(0))

color(white)("XXXXXXXX")=1875" words"
