Final answer:
Your friend will make it to school on time.
Step-by-step explanation:
To determine whether your friend will make it to school on time, we need to calculate the time it takes for your friend to bike from home to school. The formula to calculate time is distance divided by speed.
Given that your friend bikes at a constant speed of 9 miles per hour and lives 6 miles from school, we can calculate the time it takes:
Time = Distance / Speed
Time = 6 miles / 9 miles per hour
Time = 2/3 hour = 40 minutes
Since your friend leaves home 35 minutes before school starts, your friend will make it to school on time. Therefore, the answer is A) Yes.
