Answer:
James can walk 3.75 miles per hour
Step-by-step explanation:
We can use conversion factors to determine the walking speed of James in miles per hour.
James takes 120 steps/minute with each step 2.75 feet long.
∴ If one step is equal to 2.75 feet then 120 steps per minute is:
= 2.75 (feet/step) × 120(steps/minute)
Where steps cancel out and you are left with:
= 330 feet/minute
1 Foot is equal to 0.00018939 miles. Therefore we can determined miles per hour as:
= (330 feet/minute) × (0.00018939miles/foot) × (60 minutes/1 hour)
Feet cancels out with the foot and minutes cancel out with minutes and you are left with:
= 3.75 miles/hour
