Carrie can type 787 words in 12 minutes. and heather can type 1020 words in 15 minutes. who can type the fastest?

All we need to do is find out how many words they can both type per minute, WHICH we can do byyy:

Carrie:

787 / 12 = 65 (It's actually a decimal but we're just gonna keep it at 65)

Heather:

1020 / 15 = 68


SO, Heather can type 68 words per minute whereas Carrie can only type 65. Meaning Heather can type faster :D
