Question

You are in a bike race. When you get to the first checkpoint you are 2/5 of the distance away to the second checkpoint. When you get to the second checkpoint you are 1/4 of the distance to the finish. What is the distance from start to check point 1?

Answer 1

16 miles I believe because if you take the total distance and multiply that by 2/5 you get 16 hope this helps.

Answer 2

Answer: He is $\dfrac{1}{10}$ of the distance from start to check point 1.

Step-by-step explanation:

Since we have given that

When you get to the first checkpoint

he is  2/5 of the distance away to the second checkpoint.= $\dfrac{2}{5}$

When you get to the second checkpoint you are 1/4 of the distance to the finish. = $\dfrac{1}{4}$

so, the distance from start to the check point 1 is given by

$\dfrac{2}{5}\times \dfrac{1}{4}\\\\=\dfrac{2}{20}\\\\=\dfrac{1}{10}$

Hence, he is $\dfrac{1}{10}$ of the distance from start to check point 1.
