Lastly, prioritize the reading material and stay motivated to complete the task within the day. **

It is possible to hike 60 km in one day, but it would be extremely challenging and would require a high level of physical fitness and endurance. Most hikers typically cover around 20-30 km in a day, so hiking 60 km in one day would be considered an extreme feat. It would also depend on the terrain and elevation gain, as well as the individual's experience and preparation. It's important to listen to your body and not push yourself beyond your limits to avoid injury. **

Doing 60 push-ups per day can contribute to weight loss as it is a form of strength training that can help build muscle mass and increase metabolism.

A day lasts 24 hours because it is based on the Earth's rotation on its axis. The Earth takes approximately 24 hours to complete one full rotation, which is why we have 24-hour days. This rotation period has been used as the basis for our timekeeping system for centuries. If a day were 60 hours long, it would not align with the Earth's natural rotation and would not be practical for our daily activities and routines. **

It depends on the individual's fitness goals and current level of fitness.

It's important to listen to your body and adjust your training regimen accordingly. Consulting with a fitness professional can also help determine the appropriate amount of cross-training for your specific needs. **
