Answer: $40\ beats$

Step-by-step explanation:

Knowing the information provided in the exercise, you need to find the Least Common Multiple (L.C.M) in order to solve it.

You can follow these steps:

1- You must descompose 2, 5 and 8 into their prime factors:

$2=2\\5=5\\8=2*2*2=2^3$

2- And finally, you must multiply the commons and non commons with the highest exponent:

$L.C.M=2^3*5=40$

Therefore, the answer is: $40\ beats$
