Question

Suzzane can work 10 math problems in 15 minutes. How many can she word in an hour and a half?

Answer 1

Answer:

$60$

Step-by-step explanation:

Suzzane can work 10 math problems in 15 minutes. We need to use proportion and raito.

One hour and a half is equal to 90 minutes. But to equal out the math problem, change it to 900.

So:

$\frac{10}{15}$  $= \frac{x}{900}$

$= 60$

Answer 2

Answer: 1 hour and 43 min
