You walked 2⁄15 miles from your chemistry class to your economics class at a constant speed of 0.8 miles per hour. How long did this take you?

2⁄15 ÷ 0.8 = 1⁄6 hr = 10 minutes

0.13333/x = 0.8/60

0.8x = 8

x = 10

Yes, You are right. I goofed!

To find out how long it took you to walk from your chemistry class to your economics class, we can use the formula:

Time = Distance / Speed.

In this case, the distance is given as 2/15 miles, and the speed is 0.8 miles per hour. Plugging in these values, we have:

Time = (2/15) / 0.8.

To divide by a fraction, we can multiply by its reciprocal. In this case, we can rewrite the expression as:

Time = (2/15) * (1/0.8).

Evaluating the expression:

Time = (2/15) * (1/0.8) = 2/15 * 1/0.8.

Applying the multiplication:

Time = 2 * 1 / 15 * 0.8 = 2 / 12 = 1/6.

Therefore, it took you 1/6 of an hour to walk from your chemistry class to your economics class. To convert this to minutes, we know that 1 hour is equal to 60 minutes. So:

1/6 hour = (1/6) * 60 minutes = 10 minutes.

Therefore, it took you 10 minutes to walk from your chemistry class to your economics class.

Dominique drove home from work at an average speed of 36 miles per hour. If the distance from her house to her workplace is 5.4 miles, how long did her commute take?

minutes

2⁄15 = 0.13333

0.13333 * 0.8 = 0.106667 hour

60 * 0.106667 = 6.4 minutes
