Question

Julie sees a ride that spins 10 turns each minute. She says it will spin 40 turns in 4 minutes. Is Julie correct? Explain.

Answer 1

Answer: Yes she is correct

Explanation:

Answer 2

yes

Explanation:

1 minute = 10 turns

4 minutes = 40 turns

• This is direct proportion. As one side increases by a value so must the other. In this case 1 min has become 4 mins. This has been multiplied by 4. So 10 must be multiplied by 4 too. 4 × 10 = 40 turns.
