Donald can type 300 words in 10 minutes. How long will it take him to type a 1050-word essay if he types at the same rate? A. 40 minutes B. 25 minutes C. 35 minutes D. 30 minutes

Respuesta :

C. 35 minutes

300 words in 10 minutes

words/minutes = 300/10

For 1050 words:

1050 words / x minutes

1050 /x

Equal both rates:

300/10 = 1050/x

Solve for x (minutes)

30 =1050/ x

x = 1050/30

x= 35
