You are in a bike race. when you get to the first checkpoint, you are 2/5 of the distance to the second checkpoint. when you get to the second check point, you are 1/4 of the distance to the finish. if the entire race is 40 miles, what is the distance between the start and the first check point?

If the entire race is 40 miles, then the second checkpoint is 3/4 of the whole way, which is 30 miles because 40 ÷ 4 = 10 and 10 x 3 = 30. This means that there are 30 miles between the start and the second checkpoint. 2/5 of 30 is 12 because 30 ÷ 5 = 6 and 6 x 2 = 12. Therefore, the answer is 12 miles

The answer is something i don’t know

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
