Question

Two objects in outer space drift apart at an average rate of 25 kilometers every year. If the objects continue to drift apart from each other at the same rate, how many kilometers will they drift in 10 years?

Answer 1

250km Multiply the average rate by how many years and you will get your answer

Answer 2

Answer: The distance between the two objects in 10 years will be 250 kilometers.

Explanation:

We are given:

The rate at which two objects drift apart in 1 year = 25 km

To calculate the distance between the two objects in 10 years, we apply unitary method:

The distance, the two objects has drifted apart in 1 year is 25 km

So, the distance, the two objects has been drifted apart in 10 years, will be = $\frac{25}{1}\times 10=250km$

Hence, the distance between the two objects in 10 years will be 250 kilometers.
