To determine the percentage, we have to divide the value by the total value and then multiply the resultant to 100. Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6. For example, suppose we want the average of 24, 55, 17, 87 and 100. The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. One minute at 60 mph will move you 1 mile. Miles per hour is often used for car speeds. One hour walking at 1 mph moves you 1 mile. The formula can be rearranged in three ways: For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours. To solve for time, divide the distance traveled by the rate. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
