Answer 2

Answer:6024.75 seconds

Step-by-step explanation:
distance = 550m = 0.55 km
speed or rate = 80 km/hr

distance = rate*time... d= rt
Thus: t = d/r

We need to convert or units to either all
meters or all kilometers so...

t = d/r = 0.55/80 = 0.006875 hours

(0.006875 hr)(60 min/hr) = 0.4125 mins

(0.4125 min)(60 sec/min) = 24.75 seconds
