Question

Suppose that Martin finished the race 0.47 second after Kim. What was Martin's time in the race? Use an estimate to check that your answer is reasonable

Answer 1

Step-by-step explanation:

I assume that Kim finished in 50.9 seconds.

Since Martin finished the race .267 seconds after, Martin finished in .267 + 50.9.

How is adding 0.267 to 50.9 different from adding 0.26 to 50.9?

.267 + 50.9 = 51.167

.26 + 50.9 = 51.16

I think the first one is the specific number, but the second is a rounded version.
