Which of the following situations could match this formula? (There may be more than one correct answer.)

[tex]500 = 100x[/tex]

A. An object travels 500 miles at a rate of 100 miles per hour.

B. An object travels 500 feet for 100 seconds.

C. An object travels at 500 miles per hour for 100 hours.

D. An object travels 100 inches per minute for 500 minutes.

Answer :

Sure! Let's go through each option to see which situation matches the formula [tex]\(500 = 100x\)[/tex].

### Situation 1:
An object travels 500 miles at a rate of 100 miles per hour.

The formula to use here is:
[tex]\[ \text{Distance} = \text{Rate} \times \text{Time} \][/tex]

We have:
- Distance = 500 miles
- Rate = 100 miles per hour

Applying these to the formula:
[tex]\[ 500 = 100 \times x \][/tex]

This means the time [tex]\(x\)[/tex] would be 5 hours, as it fits perfectly into [tex]\(500 = 100 \times 5\)[/tex].

This situation matches the formula.

### Situation 2:
An object travels 500 feet for 100 seconds.

Using the same formula:
[tex]\[ \text{Distance} = \text{Rate} \times \text{Time} \][/tex]

We have:
- Distance = 500 feet
- Time = 100 seconds

The equation becomes:
[tex]\[ 500 = \text{Rate} \times 100 \][/tex]

Solving for the rate:
[tex]\[ \text{Rate} = 5 \text{ feet per second} \][/tex]

The equation does not fit the form [tex]\(500 = 100x\)[/tex] directly.

This situation does not match the formula.

### Situation 3:
An object travels at 500 miles per hour for 100 hours.

Using the formula:
[tex]\[ \text{Distance} = \text{Rate} \times \text{Time} \][/tex]

We have:
- Rate = 500 miles per hour
- Time = 100 hours

This gives:
[tex]\[ \text{Distance} = 500 \times 100 = 50,000 \text{ miles} \][/tex]

This is not the same as [tex]\(500 = 100x\)[/tex] because the numbers are different.

This situation does not match the formula.

### Situation 4:
An object travels 100 inches per minute for 500 minutes.

Using the formula:
[tex]\[ \text{Distance} = \text{Rate} \times \text{Time} \][/tex]

We have:
- Rate = 100 inches per minute
- Time = 500 minutes

The equation becomes:
[tex]\[ \text{Distance} = 100 \times 500 = 50,000 \text{ inches} \][/tex]

Again, this is not the same as [tex]\(500 = 100x\)[/tex].

This situation does not match the formula.

In conclusion, the situation that matches the formula [tex]\(500 = 100x\)[/tex] is:

An object travels 500 miles at a rate of 100 miles per hour.
