Answer 2

Problem Analysis

We have two motorcyclists who start simultaneously from a city in opposite directions. After 2 hours, the distance between them is 330 km. We know the speed of one motorcyclist is 87 km/h. We need to find the speed of the second motorcyclist.

Solution

Let's assume the speed of the second motorcyclist is x km/h.

After 2 hours, the first motorcyclist would have traveled a distance of 87 km/h * 2 h = 174 km.

The second motorcyclist would have also traveled a distance of x km/h * 2 h = 2x km.

The total distance between the two motorcyclists after 2 hours is given as 330 km.

So, we can write the equation: 174 km + 2x km = 330 km.

Simplifying the equation, we get: 2x = 330 km - 174 km.

Solving for x, we have: 2x = 156 km.

Dividing both sides of the equation by 2, we get: x = 78 km/h.

Therefore, the speed of the second motorcyclist is 78 km/h.

Answer

The second motorcyclist was traveling at a speed of 78 km/h.
