The number is 21. First you should divide 96 by 8 to find the 'product' that it talks about. That number is 12. So the product of 8 and 12 is 96. But, then you have to find the difference between a number and nine that makes 12. Easy! Just add 9 and 12, and you get 21 as your answer!
Answer:
The answer is: 1. 5 minutes and 2. 133.3 meters
Step-by-step explanation:
To find how long it takes the cyclist to travel 2km at 24km / hour, set up the equation and cross multiply:
2 / 24 = x / 1
24x = 2
x = 2/24 = 1/12 of an hour or 60 / 12 = 5 Minutes.
To find how far he travels in 20 seconds:
Multiply 24 km by 1000 to get meters per hour. Divide by 3600 to get meters per second:
24000 / 3600 = 6.6 meters per second.
Multiply by 20 seconds to get the distance traveled in 20 seconds:
6.6 * 20 = 133.3
Divide 27.5/11, and you get 2.5.
Austin rode for 2.5 hours (2 and a half hours).
The computation shows that the total amount or cost raised will be $250.
<h3>How to calculate the cost?</h3>
From the information given, it was stated that the skating club collected $8 from each of the nine members and had already raised $178.
Therefore, the total amount will be;
= $178 + ($8 × 9)
= $178 + $72
= $250
Therefore, the total amount raised will be $250.
