Problema Solution

Eli takes a typing test and types all 300 words in 1/10 hour. He takes the test a second time and types the words in 1/12 hour. Was he faster or slower on the second attempt? Explain

Answer provided by our tutors

Eli's rate the first time was:

300/(1/10) = 3,000 words per hour

Eli's rate the second time was:

300/(1/12) = 3,600 words per hour

Since 3,600 words per hour is more than 3,000 words per hour this means Eli was faster the second attempt.
