Circumference of fore wheel of car is 2n m and circumference of rear wheel is 3r m. If the fore wheel of the car makes 10 rotations more than the rear wheel, what is the distance covered by the car?
Let's denote the circumference of the fore wheel as \(2n\) meters and the circumference of the rear wheel as \(3r\) meters.
If the fore wheel makes 10 more rotations than the rear wheel, the distance covered by the car is equal to the circumference of the fore wheel multiplied by the number of rotations it made. The distance covered by the rear wheel is similarly the circumference of the rear wheel multiplied by the number of rotations it made.
Let \(x\) be the number of rotations made by the rear wheel. Then, the fore wheel made \(x + 10\) rotations.
The distance covered by the car is given by the sum of the distances covered by the fore and rear wheels:

If the fore wheel makes 10 more rotations than the rear wheel, the distance covered by the car is equal to the circumference of the fore wheel multiplied by the number of rotations it made. The distance covered by the rear wheel is similarly the circumference of the rear wheel multiplied by the number of rotations it made.
Let \(x\) be the number of rotations made by the rear wheel. Then, the fore wheel made \(x + 10\) rotations.
The distance covered by the car is given by the sum of the distances covered by the fore and rear wheels:
\[Distance = (2n) \times (x + 10) + (3r) \times x\]
Simplify this expression to find the total distance covered by the car.
