Answer:
t = 11.3 hours
Step-by-step explanation:
The formula d = rt stands for distance = rate x time. The problem gives you the rate, or r = 48.3 m/h, and the distance, or d = 545.79m. To solve for 't', you can plug the values given and divide:
d = rt or 545.79 = 48.3(t)
Divide both sides by 48.3: 545.79/48.3 = 48.3t/48.3
Solve for t: t = 11.3 hours
