<h3>
Answer:</h3>
43.48 mph
<h3>
Explanation:</h3>
<u>We are given;</u>
First instance;
- Distance = 50 miles
- Speed = 40 mph
Second instance;
- Distance = 20 miles
- Speed = 55 mph
We are required to determine the average speed for the entire journey.
- Average speed = Total distance ÷ total time
- We need to calculate time;
Time = Distance ÷ speed
First instance
Time = 50 miles ÷ 40 mph
= 1.25 hours
Second instance;
Time = 20 miles ÷ 55 mph
= 0.36 hours
Therefore;
Total distance = 70 miles
Total time = 1.25 hrs + 0.36 hr
= 1.61 hrs
Thus;
Average speed = 70 miles ÷ 1.61 hrs
= 43.478 miles per hour
= 43.48 mph
