Question

To determine how many minutes Scott will take to reach an elevation of 70 feet while biking upward at a rate of 10 feet per minute, follow these steps:

1. **Set Up the Equation:**

Let $$ m $$ represent the number of minutes Scott needs to bike up to 70 feet.

$$
   10 \, m = 70
   $$

Here, $$ 10 $$ feet per minute multiplied by $$ m $$ minutes equals $$ 70 $$ feet.

2. **Solve for $$ m $$ Using Division:**

To find $$ m $$, divide both sides of the equation by 10:

$$
   m = \frac{70}{10}
   $$

$$
   m = 7
   $$

So, Scott will take **7 minutes** to reach an elevation of 70 feet.

3. **Rewrite the Division Using the Multiplicative Inverse of 10:**

The multiplicative inverse of a number is its reciprocal. For 10, the multiplicative inverse is $$ \frac{1}{10} $$.

Instead of dividing by 10, you can multiply by its multiplicative inverse:

$$
   m = 70 \times \frac{1}{10}
   $$

$$
   m = 7
   $$

This confirms that $$ m = 7 $$ minutes.

**Summary:**
- **Equation:** $$ 10 \, m = 70 $$
- **Solving for $$ m $$:** $$ m = \frac{70}{10} = 7 $$ minutes
- **Using Multiplicative Inverse:** $$ m = 70 \times \frac{1}{10} = 7 $$ minutes

Therefore, Scott will reach an elevation of 70 feet in **7 minutes**.
Scott will reach an elevation of 70 feet in 7 minutes.

Scott begins mountain biking at sea level. He bikes up 10 feet every minute. How many minutes will it take his to reach an elevation of 70 feet? \( d \). Rewrite the division equation using the multiplicative inverse of 10 . Ai) \[ 10 m=70 \] \( 70 \div 10=m \)
