Shelby average speed is 30 mph in heavy traffic and his average in light traffic is 50 mph. If he was in heavy traffic for 1 hour (60min) and light traffic for 3 (180min), how far did Shelby travel?

180 Miles

Step-by-step explanation:

If she travels 30 miles per hour in heavy traffic for 1 hour you multiply 30 by 1

30 * 1 = 30

Next since she travels 50 miles per hour in light traffic for 3 hours you multiply 50 by 3

50 * 3 = 150

Add 150 and 30 to get the total distance she traveled.

150 + 30 = 180 Miles
