Question

Gavin can type 3600 words in 60 minutes.
Dan can type 3850 in 70 minutes.
Colin can type 3500 words in 70 minutes.
Who types at the fastest rate of words per minute?

Answer 1

Answer:

Gavin

Explanation:

Words typed by Gavin in 60 minutes = 3600

Words typed by Gavin per minute = 3600/60 = 60

Words typed by Dan in 70 minutes = 3850

Words typed by Dan per minute = 3850/70 = 55

Words typed by Colin in 70 minutes = 3500

Words typed by Colin per minute = 3500/70 = 50

60 > 55 > 50

Hence, Gavin types the fastest rate of words per minute.

Answer 2

Given:

• Gavin can type 3600 words in 60 minutes.
• Dan can type 3850 in 70 minutes.
• Colin can type 3500 words in 70 minutes.

To find: Who types the fastest rate of words per minute?

Solution:

[ WPM = words per minute ]

• For Gavin, WPM = 3600 / 60 = 60
• For Dan, WPM = 3850 / 70 = 55
• For Colin, WPM = 3500 / 70 = 50

Clearly we see: 60 > 55 > 50, i.e., Gavin types the fastest.

Answer: Gavin types the fastest rate of words per minute.
