Problem Analysis

We are given that a motorcyclist leaves point A with a speed of 90 km/h, and a cyclist leaves point C with a speed of 20 km/h. The distance to point B is the same for both, and it is 440 km. We need to determine how long it will take for them to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it will take for the motorcyclist to reach point B: - Distance from A to B: 440 km - Speed of the motorcyclist: 90 km/h

Using the formula, we can calculate the time it will take for the motorcyclist to reach point B: time_A_to_B = distance_A_to_B / speed_motorcyclist.

Let's calculate the time it will take for the cyclist to reach point B: - Distance from C to B: 440 km - Speed of the cyclist: 20 km/h

Using the formula, we can calculate the time it will take for the cyclist to reach point B: time_C_to_B = distance_C_to_B / speed_cyclist.

Since the motorcyclist and cyclist are traveling towards each other, the total time it will take for them to meet is the sum of the times it takes for each of them to reach point B: total_time = time_A_to_B + time_C_to_B.

Let's calculate the values:

Calculation

- Distance from A to B: 440 km - Speed of the motorcyclist: 90 km/h - Speed of the cyclist: 20 km/h

Using the formula, we can calculate the time it will take for the motorcyclist to reach point B: time_A_to_B = distance_A_to_B / speed_motorcyclist = 440 km / 90 km/h.

Using the formula, we can calculate the time it will take for the cyclist to reach point B: time_C_to_B = distance_C_to_B / speed_cyclist = 440 km / 20 km/h.

The total time it will take for them to meet is the sum of the times it takes for each of them to reach point B: total_time = time_A_to_B + time_C_to_B.

Let's calculate the values:

time_A_to_B = 440 km / 90 km/h time_C_to_B = 440 km / 20 km/h total_time = time_A_to_B + time_C_to_B

Calculation Result

Using the given values, we can calculate the following: - time_A_to_B = 4.8889 hours - time_C_to_B = 22 hours - total_time = 26.8889 hours

Answer

The motorcyclist and cyclist will meet after approximately 26.8889 hours.

Please note that the above calculations assume constant speeds for the entire journey and do not take into account any breaks or changes in speed.
