a.
To calculate: the distance travelled in meters.
a.

Answer to Problem 25PPS
The distance is
Explanation of Solution
Given information:
The equation
Formula used:
Dependent variable and Independent variable: x is independent variable whereas y is dependent variable because the value of y depends on value of x .
Calculation:
We have ,
Where
Substituting the value we get,
Hence, the distance travelled in 25 second is 260 meters.
b.
To calculate: the among two coaster which travels the faster.
b.
