Answer 2

Calculation of the Time it Takes for the Second Skier to Catch up to the First Skier

To calculate the time it takes for the second skier to catch up to the first skier, we can use the formula:

Time = Distance / Speed

Given that the initial distance between the two skiers is 4.35 km, the first skier's speed is 12.8 km/h, and the second skier's speed is 15.7 km/h, we can calculate the time it takes for the second skier to catch up to the first skier.

Let's denote the time it takes for the second skier to catch up as 't' hours.

The distance covered by the first skier in 't' hours is given by: Distance covered by the first skier = Speed of the first skier * t

The distance covered by the second skier in 't' hours is given by: Distance covered by the second skier = Speed of the second skier * t

Since the second skier catches up to the first skier when the distances covered by both skiers are equal, we can set up the equation:

Distance covered by the first skier = Distance covered by the second skier

Speed of the first skier * t = Speed of the second skier * t

Simplifying the equation, we get:

12.8 * t = 15.7 * t

The 't' value cancels out, and we are left with:

12.8 = 15.7

However, this equation has no solution, which means the second skier will not be able to catch up to the first skier.

Therefore, the second skier will not catch up to the first skier.
