Huernia zebrina, or Lifesaver plant, is one of the best in this category. Lifesaver cactus plants are easy to grow in small dish gardens or even bonsai containers. The biggest challenges with Huernia cactus care are overwatering, incorrect lighting and mealybugs.
What is the average speed on a ski? For regular downhill skiing the average is about 15-20 mph Olympic ski racing averages 40-50 mph and The fastest recorded speed is 156 mph here is my source http://www.trails.â¦com/facts_9654_how-fast-do-downhill-skiers.html.
Cruise is at 0.78 to 0.79 mach depending on the fuel consumption rate. Mach is the speed of sound and varies by altitude, temperature and air density. At 35,000 feet altitude, mach 1 is 663.5 mph for standard conditions. It is a few mph faster for lower altitudes and a few mph slower for higher altitudes. For standard conditions in the 33,000 to 39,000 typical cruise altitude, 0.78 to 0.79 mach would be 515 to 525 mph.
