Question 938282
Why bring in miles?  Just use meters per hour.
4500 meters, done in 5 hours, compute the speed in meters per hour.


If you really want with miles, then use the known unit conversions.
1 meter = 100 centimeters
1 inch = 2.54 centimeters
12 inches = 1 foot
5280 feet = 1 mile



You were told,  1609.34 meters = 1 mile.
If this true, then your unit conversion is already known.


{{{((4500*meters)/(5*hours))(1/1609.34)(mile/meters)}}}
