Answer:
Average speed of Marianne for the trip is 54 miles per hour
Step-by-step explanation:
Given that :
Distance traveled by Marianne for the trip = 178.2 miles
Time taken by Marianne to travel 178.2 miles = 3.3 hours
And, Distance = Average speed × Time taken
⇒ 178.2 = Average speed × 3.3
[tex]\implies\text{Average speed}=\frac{178.2}{3.3}\\\\\implies\text{Average speed}=\text{54 miles per hour}[/tex]
Hence, the average speed of Marianne for the trip is 54 miles per hour
