X Incorrect; Try Again; 5 attempts remaining It appears that you have determined Jessie's metabolic power. Note that you were asked to determine the metabolic energy that is needed to complete the race. Recall how to calculate this energy when the metabolic power and race time are known. 250 Metabolic power(W) Activity of 68kgindividual Typing 125 Ballroom dancing Walking at 5 km/h 380 Cycling at 15 km/h 480 Swimming at a fast crawl 800 Running at 15 km/h 1150 Part B How much metabolic energy does Jaime use to complete the course?

Answer 1

Ginen is & mass of Jessie & Jamie m=6&lg Part-a) metabolic energy of Jessi (151/hr) E=Pt t=&= 4 hr = 4 / 8x60 see. t = 16 see E= 1150X16 E sessie 18400) Joule Part-(b) for Jamie (5km/h) E = Pt t= 4 = 48x60 = 488 e. E=360x48 18240 Towe Jamie
