Two days left

It is only two days until the Math exam. I made 8 Math exercises today and continuing to do them later. Meanwhile I've made some self-made exercises.
Here are they:
1. A tornado was sighted in two weather services in Laguja. One weather service, Lepiku Meteorological Agency saw tornado at 50 degrees. Koru Weather Service at 2 kilometers SouthEast(160°) saw it in a direction of 20 degrees. How far was it from both weather services?
2. An eye of the hurricane was moving 400 kilometers during 7 hours. It was moving 4 hours with its usual speed, 3 hours with speed 5 kilometers per hour higher. How fast was the eye moving? How much distance it passed during these two speeds?
3. During June 2005, it is possible that Laguja would get hit by 7 thunderstorms. 3 of them contain tornadoes, 2 of tornadic storms contain also hail. 4 of thunderstorms don't contain tornadoes, but 2 of non-tornadic storms contain hail. What is the chance to get hit by a tornado? What is the chance to get hit by hail with and without a tornado? What is the chance to get hit by a thunderstorm in June?

Well, I am watching a TV a bit and then back to school books!
