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.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
