6.8 min / 1 mile
30 min * 1 mile/6.8 min = 4.41 miles
30 min * 1 mile/6.8 min = 4.41 miles
Sheldon's running time per mile is 6 4/5 minutes, or in decimal form, 6.8 minutes.
So, to calculate the number of miles Sheldon can run in 30 minutes, we divide 30 by 6.8:
30 minutes รท 6.8 minutes/mile = 4.41 miles
Therefore, Sheldon can run approximately 4.41 miles in 30 minutes.
First, let's convert the mixed number 6 4/5 into an improper fraction. To do this, we multiply the whole number (6) by the denominator (5), and then add the numerator (4). This gives us (6 * 5) + 4 = 30 + 4 = 34.
So, Sheldon can run 34/5 (or 6 and 4/5) miles in 1 minute.
To find out how many miles he can run in 30 minutes, we multiply the number of miles he can run in 1 minute by 30.
(34/5) * 30 = (34 * 30) / 5
To simplify this fraction, we multiply the numerator by the whole number (34 * 30 = 1020).
1020/5 = 204
Therefore, Sheldon can run approximately 204 miles in 30 minutes.
