In a triathlon, participants swim fer 7'50 m, bike for 30 km, and run for 5 km. If the time taken to complete the entire course is 1.5 h, the average speed, expressed in the proper manner. is (Assume all distances are accurate to the number of digits given.) 0 1) 24 kmfh O 21 2 x 101 kmfh O 3) 23.333 kmfh O 41 23.33 kmfh O 5} 23.3 kmz'h \fA bail is thrown up in the air and then caught at the same height.
