Answer:
The average speed of the journey was 70 miles per hour.
Step-by-step explanation:
To calculate the average speed in miles per hour, we need to divide the total distance traveled by the total time taken.
Given:
- Distance traveled = 140 miles
- Time taken = 120 minutes
First, we need to convert the time from minutes to hours:
120 minutes ÷ 60 minutes/hour = 2 hours
Now, we can calculate the average speed:
Average speed = Distance ÷ Time
Average speed = 140 miles ÷ 2 hours
Average speed = 70 miles per hour
Therefore, the average speed of the journey was 70 miles per hour.
