Question

A carousel spins at a rate 2 miles in 7 minutes

What is the speed in miles per minute

Answer 1

0.29 miles per minute.

Explanation:

• Speed, s, is defined by the distance, d, divided by the time, t ⇒
  `s = (d)/(t)`.

• The distance the carousel travels is 2 miles.
• The time it takes for the carousel to travel the total distance is 7 minutes.
• Therefore,
  `Speed = (2 miles)/(7 minutes)`.
• Speed is equal to 0.285 or 0.29 miles per minute.
• A common mistake would be to divide the amount of time by the distance, resulting in an incorrect answer.
