Problem: The world record for the womens outdoor 20,000 meter run, set in 2000 by Tegla Loroupe, is 1:05:26.6 (seconds are given to the nearest tenth).What was her average speed, expressed in miles per hour with the correct number of significant figures? (Assume that the race distance is accurate to 5 significant figures.)

FREE Expert Solution

We have to calculate the average speed of a runner in mi/h units.


Speed is defined as distance covered per unit time.

speed = distancetime


We will solve this problem through these steps:

Step 1: Convert distance form meter units to miles units.

Step 2: Convert time to hours.

Step 3: Calculate speed of the runner.
