Problem Analysis

We have two motorcyclists who start simultaneously from the same city in opposite directions. We are given the speed of the first motorcyclist, and the speed of the second motorcyclist for different time intervals. We need to find the distance between them.

Solution

To find the distance between the two motorcyclists, we can calculate the distance traveled by each motorcyclist and then subtract the two distances.

Let's calculate the distance traveled by each motorcyclist:

- The first motorcyclist travels at a speed of 120 km/h. We don't have the time traveled by the first motorcyclist, so we cannot calculate the distance traveled by the first motorcyclist.

- The second motorcyclist travels at a speed of 90 km/h for 2 hours and then at a speed of 110 km/h for the next 2 hours. Let's calculate the distance traveled by the second motorcyclist:

- Distance traveled at 90 km/h for 2 hours: distance_1 = speed_1 * time_1 = 90 km/h * 2 hours = 180 km - Distance traveled at 110 km/h for 2 hours: distance_2 = speed_2 * time_2 = 110 km/h * 2 hours = 220 km

Now, let's calculate the total distance between the two motorcyclists:

- Total distance = distance traveled by the second motorcyclist - distance traveled by the first motorcyclist - Total distance = (distance_1 + distance_2) - distance traveled by the first motorcyclist

Since we don't have the distance traveled by the first motorcyclist, we cannot calculate the total distance between the two motorcyclists.

Unfortunately, we don't have enough information to calculate the distance between the two motorcyclists.
