Question

It took 3.3 hours for Marianne to drive 178.2 miles.What was her average speed for the trip?

Answer 1

the formula for speed is distance/time so 178.2/3.3= 54miles/h

Answer 2

Average speed of Marianne for the trip is 54 miles per hour

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

`\implies\text{Average speed}=(178.2)/(3.3)\\\\\implies\text{Average speed}=\text{54 miles per hour}`

Hence, the average speed of Marianne for the trip is 54 miles per hour
