Answer 3

To determine if the motorcyclist will arrive on time in city M, we need to calculate the total time it will take for the motorcyclist to travel from the starting point to city M.

Calculation:

- Distance from the starting point to city M: 320 km - Speed in the first hour: 75 km/h - Speed for the remaining time: 75 km/h

To calculate the total time, we can divide the distance by the average speed: - Time taken in the first hour: 1 hour - Time taken for the remaining distance: (320 km - 75 km) / 75 km/h = 3.46 hours (rounded to two decimal places)

Adding up the time taken in the first hour and the time taken for the remaining distance, we get: - Total time taken: 1 hour + 3.46 hours = 4.46 hours (rounded to two decimal places)

Since the motorcyclist is expected to arrive in city M 5 hours after departure, it is clear that the motorcyclist will arrive on time, as the total time taken is less than the given time of 5 hours.

Therefore, the motorcyclist will arrive on time in city M.
