Percentage can be found by turning the numbers into a fraction and dividing them. In this case, it would be organized like so: 15/38. This gives you 0.39, which is equal to 39%.
Let the speed of one rider = x
The speed of the second rider would e 2x ( twice as fast)
The total speed of the two riders would be x + 2x = 3x
Speed = Distance / time
Using the numbers:
3x = 72/3
Simplify:
3x = 24
Divide both sides by 3:
x = 8
The speed of one rider is 8 miles per hour
The speed of the second rider is 2(8) = 16 miles per hour.

Answer:
<h2>14</h2>
Step-by-step explanation:
Given the expression 3.2 + 2^3, we are to simplify and find the value of the expression.
Note that the dot means multiplication. The equation then becomes;
<em>Hence the value of the expression is 14</em>
