The IQR is the upper quartile-lower quartile. The way to determine this is finding the median of your numbers which is 53. Then you take the numbers higher than 53 and find the median of those which is 63.5. 63.5 is the upper quartile. Then you take the bottom half under 53 and find the median of those. The median of this is 53.5 53.5 is the lower quartile. Then just subtract 63.5-53.5 and you will get 10 as the IQR.

Since there are 5,280 feet in one mile and 3.3 feet in one meter, how many meters per second are equivalent to 60 miles per hour
svlad2 [7]
Given:
1 mile = 5280 feet
1 meter = 3.3 feet

convert 60 miles per hour to meters per second

60 miles to meters

60 miles x <u>5280ft</u> x <u>1meter</u> = (60*5280m)/3.3 = 316800m/3.3
                  1 mile    3.3ft
= 96,000 meters

1 hour to seconds

1 hour x <u>60 minutes</u> x <u>60 seconds</u> =   1 * 60 * 60sec = 3600 seconds 
                1 hour            1 minute

unit rate: meters per second

96000 meters ÷ 3600 seconds = 26 2400/3600 
simplify 26 2400/3600 ⇒ 26 2/3 meters per second

2400 ÷ 1200 = 2
3600 ÷ 1200 = 3
