The iron man triathlon competition has three events: swimming, cycling and running. One participant swam 10km in one hour, rode a bike 140km averaging 20km/h and then ran 24km averaging 10 minutes per km. What was iron man's average speed for the entire 174km of competition???

    first try to find the amount of time in hours and the speed in km/h for each event, the last one is tricky so if its 24km and the speed is 10min/km its 24*10 so 240 mins=4 hours and since its 4 hours to run 24km then its 24/4 so 6 km/hr.

    add up the speeds per distance travelled divided by the total different modes travelled (run, ride, swim would be 3 )
