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.
