Officer Kim is on her way to Melissa’s house, traveling 59 miles per hour.  Officer Kim lives 29 miles from Melissa’s house.

Estimate the amount of time it will take Officer Kim to arrive at Melissa’s house.

  1. 60 minutes
  2. 1 hour
  3. A half hour
  4. 20 minutes
Explanation

Answer: C - It will take approximately a half hour to get to Melissa’s house. Instead of finding the exact solution, it is sometimes easier to estimate. If you estimate that 59 is close to 60 and 29 is close to 30, it is easier to see that she travels at the rate of one mile per minute. Since Officer Kim is approximately 30 miles away, arriving should take about 30 minutes or a half hour.
