Mikayla can run 2 miles in 12 1/2 minutes. Brie can run 5 miles in 22 1/4 minutes. Who can run faster?
check the time per mile
22.25/4 < 12.5/2
or, just note that Mikayla takes 25 minutes to run only 4 miles,
while Brie runs farther in less time
Well, let's do some clown math here!
Mikayla runs 2 miles in 12 1/2 minutes. So, how many miles can she run in 1 minute?
If we divide 2 by 12 1/2, we get 0.16 miles per minute. That's Mikayla's running speed!
Now let's calculate Brie's running speed. She can run 5 miles in 22 1/4 minutes. So, how many miles can she run in 1 minute?
If we divide 5 by 22 1/4, we get 0.23 miles per minute. That's Brie's running speed!
So, after all that clown math, Brie can run faster than Mikayla! She's a speed demon in comparison. You go, Brie!
To determine who can run faster, we need to compare the rates at which Mikayla and Brie can run. We can calculate their rates by dividing the distance they can run by the time it takes them.
Let's start with Mikayla:
- Distance: Mikayla can run 2 miles
- Time: Mikayla can run in 12 1/2 minutes, which is equal to 12.5 minutes.
To find Mikayla's rate, we divide the distance by the time:
Rate = Distance / Time
Mikayla's rate = 2 miles / 12.5 minutes
Now, let's move on to Brie's running rate:
- Distance: Brie can run 5 miles
- Time: Brie can run in 22 1/4 minutes, which is equal to 22.25 minutes.
To find Brie's rate, we divide the distance by the time:
Rate = Distance / Time
Brie's rate = 5 miles / 22.25 minutes
Now, we can compare their rates to determine who can run faster. We'll calculate their rates and compare them.
Mikayla's rate = 2 miles / 12.5 minutes = 0.16 miles/minute
Brie's rate = 5 miles / 22.25 minutes = 0.22 miles/minute
Comparing the two rates, we can see that Brie's rate is higher at 0.22 miles/minute. Therefore, Brie can run faster than Mikayla.
To determine who can run faster, we need to compare their running speeds. The running speed can be calculated by dividing the distance covered by the time taken.
For Mikayla:
Distance = 2 miles
Time = 12 1/2 minutes = 12.5 minutes
Running Speed = Distance / Time
Mikayla's Running Speed = 2 miles / 12.5 minutes
For Brie:
Distance = 5 miles
Time = 22 1/4 minutes = 22.25 minutes
Running Speed = Distance / Time
Brie's Running Speed = 5 miles / 22.25 minutes
Now, we can compare their running speeds. Simply compare the calculated running speeds of Mikayla and Brie. The one with the higher running speed is the faster runner.
