The triathlete swam 2 miles in 56 minutes. Then, he rode his bicycle 100 miles in 5 hours. Finally, he ran 20 miles in 106 minutes. How many minutes did it take him to complete the course? During which portion of the race did he have the greatest average speed?

Uh Duh

Steve
you aint gotta be rude she just asked a simple question so get on with yourself

UH- DUH!

UH- DUH! I actually have no idea lol. I'm too lazy to do math.

To calculate the total time it took the triathlete to complete the course, we need to add the time it took for each portion of the race.

The triathlete swam for 56 minutes, rode his bike for 5 hours (which is equivalent to 5 * 60 = 300 minutes), and ran for 106 minutes. Let's add these times together:

56 minutes (swimming) + 300 minutes (cycling) + 106 minutes (running) = 462 minutes

Therefore, it took the triathlete 462 minutes to complete the entire course.

To determine which portion of the race the triathlete had the greatest average speed, we need to calculate the average speed for each activity. Average speed is defined as distance divided by time.

For the swimming portion, the triathlete swam 2 miles in 56 minutes. So, the average speed is:

2 miles / 56 minutes = 0.036 miles per minute

For the cycling portion, the triathlete rode 100 miles in 300 minutes. The average speed is:

100 miles / 300 minutes = 0.333 miles per minute

Finally, for the running portion, the triathlete ran 20 miles in 106 minutes. The average speed is:

20 miles / 106 minutes = 0.188 miles per minute

Comparing these average speeds, we can see that the triathlete had the greatest average speed during the cycling portion of the race, with an average speed of 0.333 miles per minute.

duh - just add up the times.

for part 2, which is the greatest?

2/56 or 100/5 or 20/106

that's easy, right?
