It will take 8 minutes.
You use a proportion 
5/1=2400/x you use 2400 because 2.4km=2400 meters and u need to use the same unit of measurement.
so cross multiplying gives you 5x=2400 which is equal to 480. BUT this is 48 seconds, and it asks you how many minutes, not seconds. So, you divide by 60 because there are 6 seconds in a minute, and you get 8.

Brenda had bowling scores of 92, 110, 85, 78, and 96. She completed the steps below to determine the score she needs in her next
Yakvenalex [24]

Answer:

<u>Hence final answer is B: Step 2.</u>

Step-by-step explanation:

Step 1: Find the total points needed to score in six games: 96x6=576

Justification:

Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.


Step 2: Find the total points scored: 92+110+85+78=365

Justification:

Sum of total points scored by Brenda is 92+110+85+78= 461.

But she got different value 365.

Hence step 2 is wrong.


<u>Hence final answer is B: Step 2.</u>
