Answer 1

Calculation of Distance Traveled by the Cyclist

To calculate the total distance traveled by the cyclist, we need to consider the different segments of the journey separately.

1. First 10 minutes at a speed of 4 m/s: - Convert the speed from m/s to km/h: 4 m/s = 14.4 km/h. - Calculate the distance traveled in 10 minutes: (14.4 km/h) x (10/60) h = 2.4 km.

2. Remaining time at a speed of 36 km/h: - Convert the speed from km/h to m/s: 36 km/h = 10 m/s. - Calculate the time spent at this speed: 60 minutes - 10 minutes - 1 minute = 49 minutes. - Calculate the distance traveled at this speed: (10 m/s) x (49/60) h = 8.17 km.

3. 1 minute descent at a speed of 54 km/h: - Calculate the distance traveled during this time: (54 km/h) x (1/60) h = 0.9 km.

To find the total distance traveled, we sum up the distances from each segment: 2.4 km + 8.17 km + 0.9 km = 11.47 km.

Therefore, the cyclist traveled a total distance of approximately 11.47 km during the entire journey.
