Question

Iris can type 60 words per minute. Jamie types 1.5 times as fast as Iris. How many words can Jaime type in 10 minutes?

Answer 1

Hi there! Hope this helps!

Explanation:

Since Jamie can types 1.5 times more than Iris, then it would be 60 x 1.5 = 90. Then, if Jamie can types 90 words in a minute, she can type 900 word in 10 minutes: 90 x 10 = 900.
