Final answer:
Shyawn walked 880 yards in 15 minutes and Diego walked 5,280 feet in 20 minutes. To compare their speeds, we convert the distances and times to the same units and then divide the distances by the times. Diego walked approximately 2.77 mph faster than Shyawn.
Step-by-step explanation:
To compare the speeds of Shyawn and Diego, we need to convert their distances and times into the same units. Let's start by converting Shyawn's distance of 880 yards to feet. Since 1 yard is equal to 3 feet, Shyawn walked 880 yards * 3 feet/yard = 2640 feet. Next, let's convert the time of 15 minutes into hours. We know that 1 hour is equal to 60 minutes, so Shyawn walked for 15 minutes / 60 minutes/hour = 0.25 hours.
Now let's convert Diego's distance of 5280 feet to miles. Since 1 mile is equal to 5280 feet, Diego walked 5280 feet / 5280 feet/mile = 1 mile. We also need to convert his time of 20 minutes into hours. Using the same conversion, Diego walked for 20 minutes / 60 minutes/hour = 0.33 hours.
To calculate the speeds, we divide the distances by the times. Shyawn's speed is 2640 feet / 0.25 hours = 10560 feet per hour. Diego's speed is 1 mile / 0.33 hours = 3.03 miles per hour. To calculate how much faster Diego walked than Shyawn, we subtract Shyawn's speed from Diego's speed: 3.03 miles per hour - 10560 feet per hour = 2.77 miles per hour.
Therefore, Diego walked approximately 2.77 mph faster than Shyawn.
