Raquel can type 63 words every minnute. Rick type then Raquel in 135 minute? Circle the letter of the correct answer. A 1350 B 4599 C 8505 D 9855? Jared chose as the correct answer. How did he get that answer?

Answer: 1350

Step-by-step explanation:

Here is the correct question.

Raquel can type an average of 63 words per minute. Rick can type 73 words per minute. how many more words can Rick type than Raquel in 135 minutes? Jared chose B as the correct answer. How did he get that answer? Jared said the answer is 4599. How did he get that answer?

Rick's word per minute = 73

Raquel's word per minute = 63

Ricks word in 135minute = 73*135 = 9855

Raquel's word in 135 minutes=63*135 = 8505

=9855 - 8505

= 1350

Rick can type 1350 more words than Raquel in 135 minutes.

Jared's answer is wrong. He got the answer by multiplying 63 by 73 which gives 4599.

Step-by-step explanation:

Given:

Typing rate of Raquel, Tx = 63 words per minute

Typing rate of Rick, Ty = 73 words per minute

Time taken, s = 135 minutes

Typing rate, T = number of words, R/time taken, s

In 135 minutes, Raquel will type,

Rx = Tx * s

= 63 * 135

= 8505 words.

In 135 minutes, Rick will type,

Ry = Ty * s

= 73 * 135

= 9855 words

Delta R = Ry - Rx

= 9855 - 8505

= 1350 words

Option A

Jared calculation was,

= Typing rate of Raquel, Tx * Typing rate of Rick, Ty

= 73 * 63

= 4599 words
