Question

PLS ANSWER QUICK!!!! (FOR MY PROJECT)

Pedro observes a marble travel along a horizontal path at a constant rate. The marble travels 1/15 of the length of the path in 2 2/5 seconds seconds. At that rate, how many seconds does it take the object to travel the full length?

Answer 1

12/75 or if simplified 4/25

Explanation:

1/15 x 2 2/5, 5x2 + 2 = 12, 1x12, 15x5, = 12/75. If you simplify that it is 4/25.

Answer 2

36 seconds

Explanation:

2 2/5 = 12/5

If the marble travelled 1/15 of the length of the path in 12/5 seconds, then to get to the full length of 1, as it's a constant rate, you'd multiply 12/5 by 15 (as 1/15 x 15 = 1).

`(12)/(5)` x 15 = 12 x 3 = 36 seconds.
