To determine how many miles a cyclist rides in seven hours at an average speed of 18 miles per hour, we can follow a simple calculation using the formula for distance:
### Formula for Distance
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]
### Given Data
- Speed: 18 miles per hour
- Time: 7 hours
### Calculation
[tex]\[ \text{Distance} = 18 \, \text{miles/hour} \times 7 \, \text{hours} \][/tex]
[tex]\[ \text{Distance} = 126 \, \text{miles} \][/tex]
So, the cyclist rides 126 miles in seven hours.
### Final Answer
The correct answer is:
126
