moe ran 3/4 a mile in 15 minutes.if he runs at the same constant rate of speed how long will it take him to run one mile
( 3 / 4 mile ) / 15 min = 1 mile / x min
You can write that like:
( 3 / 4 ) / 15 = 1 / x
3 / ( 4 * 15 ) = 1 / x
3 / 60 = 1 / x
3 / 3 * 20 = 1 / x
1 / 20 = 1 / x
Cros multiply
x * 1 = 20 * 1
x = 20 min
OR
15 min = 1 / 4 h
Speed = Distance / time
Speed = ( 3 / 4 ) / ( 1 / 4 ) = 3 mile / h
1 mile = ( 1 / 3 ) of 3 mile
Time for one mile = ( 1 / 3 ) of 1 h = 60 min / 3 = 20 min
r = 0.75mi./15min = 0.05 mi/min.
d = r * t.
1 = 0.05 * t,
t = ?
To find out how long it will take Moe to run one mile, we can use the information given in the question.
We know that Moe ran 3/4 of a mile in 15 minutes. To find his speed, we can divide the distance he ran by the time it took.
So, Moe's speed is (3/4 mile) / (15 minutes) = 1/20 mile per minute.
Now, we need to determine how long it will take him to run one mile at this constant speed. We can set up a proportion:
(1 mile) / (x minutes) = (3/4 mile) / (15 minutes)
To solve for x, we can cross-multiply:
1 * 15 = (3/4) * x
15 = (3/4) * x
Next, we can simplify the equation by dividing both sides by 3/4:
15 / (3/4) = x
15 * (4/3) = x
20 = x
Therefore, it will take Moe 20 minutes to run one mile at the same constant speed.
