Question

The number of trains in operation in 1990 was 800. The number of trolleys in 2005 was 905. Find the rate of change.

a. Not provided.
b. Calculate based on given data.
c. Data missing.
d. None of the above.

Answer 1

To find the rate of change, subtract the number of trains in 1990 from the number of trains in 2005, then divide by the number of years between the two dates. The rate of change is 7 trains per year.

Step-by-step explanation:

To find the rate of change, we need to calculate the difference between the number of trains in operation in 2005 and 1990, and then divide that difference by the number of years between 2005 and 1990.

So, the rate of change can be calculated as:

Rate of Change = (Number of trains in 2005 - Number of trains in 1990) / (Year in 2005 - Year in 1990)

Rate of Change = (905 - 800) / (2005 - 1990)

Rate of Change = 105 / 15

Rate of Change = 7 trains per year
