Julie sees a ride that Spins 10 turns each minute. She says it will spin 40 turns in 4 minuets. Is Julie correct? Explain.
Solution
Yes, she is Correct.
Here is the explanation.
Step 1: Write it in ratio form.
10 turns = 1 minutes
10: 1 = 10/1
40 turns = 4 minutes
40:4 = 40/4
Step 2: Form a proportion. They are in proportion.
10/1 = 40/4
Step 3: Now we have to cross multiply and check if it is true.
10*4 = 40*1
40 = 40
Which is true.
Therefore, Julie is correct.
That's it.
Thank you :)
