Brett and Jim sign up for Memorial Day race in their town. There are two different events, a 5 kilometers and a 10 kilometers. Brett signed for 5 kilometers and Jim signed for 10 kilometers. Use thermometers to indicate when both Brett and Jim have finished 3/5 of their races. How many kilometers has each person run at this point?
Use thermometers?
(3/5) * 5 = 15/5 = 3 km
(3/5) * 10 = ?
To find out how many kilometers each person has run when they have finished 3/5 of their races, we first need to calculate how many kilometers each person needs to run.
Brett signed up for the 5 kilometers race, so to find out 3/5 of 5 kilometers, we can multiply 5 by 3/5:
5 km * 3/5 = 15/5 = 3 kilometers
Therefore, Brett has run 3 kilometers by the time he has completed 3/5 of his race.
Jim signed up for the 10 kilometers race, so to find out 3/5 of 10 kilometers, we can multiply 10 by 3/5:
10 km * 3/5 = 30/5 = 6 kilometers
Therefore, Jim has run 6 kilometers by the time he has completed 3/5 of his race.
In summary, Brett has run 3 kilometers, and Jim has run 6 kilometers when they have both finished 3/5 of their races.
