Atrain tavels 7/16 of a mile in 1/4 of a minute. at what rate does the car travel, in miles per minute?

The car can travel 7/4 miles in a minute.

Step-by-step explanation:

In order to determine the amount of miles in a whole minute, we need to find the amount to multiply the minute amount by to get a whole minute. Since the expression is currently written as 1/4, we multiply by the reciprocal to get to 1. The reciprocal of 1/4 is 4.

Now that we have that, we need to multiply the mile amount by the same factor.

7/16 * 4 = 7/4 miles

Therefore, you can travel 7/4 miles in a minute.

a negative exponent is translated as follows:

so, we have
