3 PART
Claire and Malia are training for a race
A)Claire runs 10 km in 1 hour. How many kilometers does she run in half an hour? In 2 1/2 hours?
B)Malia runs 5 miles in 1 hour. How many miles does she run in half an hour? In 2 1/2 hours?
C)On Tuesday, Claire and Malia both ran for 2 1/2 hours. Who ran the farther distace?
THANK YOU!
as usual, just recall that
distance = speed * time
Now just plug in your numbers...
160*2/1half
A) To find how many kilometers Claire runs in half an hour, we can divide the distance she runs in 1 hour by 2:
1 hour / 2 = 0.5 hours
Since Claire runs 10 kilometers in 1 hour, she would run 5 kilometers in half an hour.
To find how many kilometers Claire runs in 2 1/2 hours, we can multiply the distance she runs in 1 hour by 2.5:
10 kilometers/hour * 2.5 hours = 25 kilometers
B) To find how many miles Malia runs in half an hour, we can divide the distance she runs in 1 hour by 2:
1 hour / 2 = 0.5 hours
Since Malia runs 5 miles in 1 hour, she would run 2.5 miles in half an hour.
To find how many miles Malia runs in 2 1/2 hours, we can multiply the distance she runs in 1 hour by 2.5:
5 miles/hour * 2.5 hours = 12.5 miles
C) To compare the distances Claire and Malia ran on Tuesday, we need to compare the distances they ran in 2 1/2 hours. From the previous calculations, we know that Claire ran 25 kilometers and Malia ran 12.5 miles.
To compare the distances, we need to convert one of the values to the same unit. Let's convert Malia's distance from miles to kilometers:
1 mile = 1.60934 kilometers (approximately)
12.5 miles * 1.60934 kilometers/mile ≈ 20.12 kilometers
Comparing the distances, Claire ran 25 kilometers and Malia ran approximately 20.12 kilometers. Therefore, Claire ran the farther distance.
A) To find out how many kilometers Claire runs in half an hour, you can divide the distance she runs in 1 hour by 2. Since Claire runs 10 km in 1 hour, she would run half of that distance, which is 5 km, in half an hour.
To find out how many kilometers Claire runs in 2 1/2 hours, you can multiply the distance she runs in 1 hour by 2.5. Since Claire runs 10 km in 1 hour, she would run 25 km in 2 1/2 hours.
B) To find out how many miles Malia runs in half an hour, you can divide the distance she runs in 1 hour by 2. Since Malia runs 5 miles in 1 hour, she would run half of that distance, which is 2.5 miles, in half an hour.
To find out how many miles Malia runs in 2 1/2 hours, you can multiply the distance she runs in 1 hour by 2.5. Since Malia runs 5 miles in 1 hour, she would run 12.5 miles in 2 1/2 hours.
C) To determine who ran the farther distance in 2 1/2 hours, we compare the distances Claire and Malia ran. Claire ran 25 km in 2 1/2 hours, and Malia ran 12.5 miles in 2 1/2 hours. We need to convert Malia's distance to kilometers since Claire's distance is in kilometers.
To convert miles to kilometers, we use the conversion rate of 1 mile = 1.60934 kilometers.
So, Malia's distance in kilometers would be 12.5 miles * 1.60934 kilometers/mile = 20.1175 kilometers.
Comparing the distances, we see that Claire ran 25 km, while Malia ran 20.1175 km. Therefore, Claire ran the farther distance.
