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.
