minutes

Answer 1

To find out how many minutes Mr. Ivey’s students spend on strength and conditioning in each class, we can set up a proportion.

1. We know that the class is 90 minutes long.
2. Mr. Ivey spends 94% of that time teaching strength and conditioning.

First, we convert the percentage to a decimal:

\[ 94\% = \frac{94}{100} = 0.94 \]

Next, we calculate the amount of time spent on strength and conditioning:

\[
\text{Time on strength and conditioning} = \text{Total class time} \times \text{Percentage spent on strength and conditioning}
\]
\[
\text{Time on strength and conditioning} = 90 \text{ minutes} \times 0.94
\]
\[
\text{Time on strength and conditioning} = 84.6 \text{ minutes}
\]

Therefore, Mr. Ivey’s students spend **84.6 minutes** on strength and conditioning in each class.
