Step-by-step explanation:
let X = speed of slow bicycle rider
2x=speed of fast bicycle rider
3(x+2x)=72
X=8mph(slowest bicycle rider)
2x=16mph(fastest bicycle rider)
For this case we have to:
x: Represents the unknown number
y: Represents the exponent of base 10
So, considering a system of equations we have:

From the first equation we have:

Substituting in the second equation:

We choose the positive value:

So, the number is 0.4.
So:

Thus, the exponent is 5.
