You walked 2/15 miles from your chemistry class to your ecenomics class at a constant speed of 0.8 miles per hour. How long did this take you.
To find the time it took to walk the distance, we can divide the distance walked by the speed:
Time = Distance / Speed
Given that you walked 2/15 miles and had a speed of 0.8 miles per hour, we can plug in the values to find the time:
Time = (2/15) / 0.8 = (2/15) * (1/0.8) = 2/12 = 1/6 hour.
Therefore, it took you 1/6 hour to walk from your chemistry class to your economics class.
To find the time it took you to walk 2/15 miles at a constant speed of 0.8 miles per hour, you can use the formula time = distance / speed.
The distance you walked is 2/15 miles, and the speed is 0.8 miles per hour.
Plugging these values into the formula, we get:
time = (2/15 miles) / (0.8 miles per hour)
To divide by a fraction, you can multiply by its reciprocal:
time = (2/15 miles) * (1 / (0.8 miles per hour))
Simplifying the expression on the right side, we get:
time = (2/15) * (1 / 0.8) hours
Now, let's evaluate the expression:
time = 2/15 * 1/0.8
= 2/15 * 1.25
= 0.1667 * 1.25
= 0.2084 hours
Therefore, it took you approximately 0.2084 hours to walk from your chemistry class to your economics class.
To find out how long it took you to walk from your chemistry class to your economics class, you can use the formula for speed, which is distance divided by time.
In this case, the distance you walked was 2/15 miles and your speed was 0.8 miles per hour.
Let's use the formula to find the time it took:
Time = Distance / Speed
Time = (2/15) miles / 0.8 mile/hour
To divide by a fraction, you can multiply by its reciprocal. The reciprocal of 0.8 is 1/0.8, which is 1.25.
Time = (2/15) miles * (1.25 hour/mile)
When you multiply the fractions, you multiply the numerators (top numbers) together and the denominators (bottom numbers) together.
Time = (2 * 1.25) / (15 * 1) hours
Time = 2.5 / 15 hours
To simplify this fraction, you can divide the numerator and denominator by their greatest common divisor, which is 5.
Time = (2.5 ÷ 5) / (15 ÷ 5) hours
Time = 0.5 / 3 hours
Finally, we can convert the fraction to a decimal by dividing 0.5 by 3.
Time = 0.1667 hours
Since time is typically measured in hours, we can convert this to minutes by multiplying by 60.
Time = 0.1667 hours * 60 minutes/hour
Time ≈ 10 minutes
So, it took you approximately 10 minutes to walk from your chemistry class to your economics class.
