Answer:
285 min
275 min
chi
tie
Step-by-step explanation:
swim - 1.5 km
bicycle ride - 40 km
run - 10 km
1) Alexandra
swim time = distance / velocity = 1.5 / 5 = 0.3 hr = 18 min
transition 1 time = 4 min
cycling time = distance / velocity = 40 / 15 = 2.6666667 hr = 160 min
transition 2 time = 3 min
run time = distance / velocity = 10 / 6 = 1.6666667 hr = 100 min
so total time to complete the triathlon is
= 18 + 4 +160 + 3 +100
= 285 min = 4.75 hrs
2) Chi
swim time = distance / velocity = 1.5 / 6 = 0.25 hr = 15 min
transition 1 time = 5 min
cycling time = distance / velocity = 40 / 15 = 2.6666667 hr = 160 min
transition 2 time = 5 min
run time = distance / velocity = 10 / 7.5 = 1.3333333 hr = 80 min
got flat tire that took 10 min to fix
so total time to complete the triathlon is
= 15 + 5 + 160 + 5 + 80 + 10
= 275 min
3) Alexandra won the race by 10 min
4)even though chi got flat tire , chi still won the race by 10 min,
if it took 20min to fix flat tire both their times would be 285 min and it would have been a tie.
