Question 621569: Ok, I hope you can help it's been driving me nuts for a while now. Train leaves at 9 am at a speed of 65km/hr straight. At 10:30 am a car leaves the same station at 115km/hr. A) How far from the station does the car catch up with the train? B) What was the cars average velocity in meters per second? C) If the car had not left the train station until 11am and the train still travels at 65km/hr, how fast would the car have to go to catch up to the train at the same distance from the station as in part A in Km/hr?

Question 622174: On a day with no wind, a hot-air balloon hovers at a point above a long, straight river. On the west side of the balloon a sailboat is spotted in the river at an angle of depression of 48 degrees. On the east side, a canoe spots the balloon at an angle of inclination of 29 degrees. The distance between the balloon and the canoe is 650 m.
a) What is the height of the balloon?
b) What is the distance between the balloon and the sailboat?
c) What is the distance between the sailboat and the canoe?
I really need help, thanks in advance!
Im not sure if I am solving this correctly but this is what I have done:
Sin 29 = h/650
650 x sin 29 = 315.1
Therefore the height of the balloon is 315.1 m.
B) Sin 48 = h/650
650 x sin 48 = 483.0
Therefore the distance between the balloon and the sailboat is 483m
C) 650 + 483 = 1133
Therefore the distance between the sailboat and the canoe is 1133 m

Question 621985: when a truck travels 60kmph, it uses 30% more fuel to travel any distance than it takes when it travels at 50kmph. the truck can travel 20 km on a litre of fuel if it is travelling at 50kmph. the truck has only 10 litre of fuel in the tank and is 160km from its destination. If it takes 20 minutes for the truck to fill the fuel, how long will the truck take to reach its destination if it is driven at 60kmph?

Question 622224: A rocket carrying a weather satellite is launched. As it moves through space, the rocket is tracked by two tracking stations located 24 km apart, beneath the rocket. The two tracking stations both lie west of the launching pad and are located on a straight line from the launching pad. At a specific moment, the rocket's angle of elevation from Station X is 40 degrees while the rocket's angle of elevation from Station Y is 70 degrees. Both tracking stations are west of the rocket at this moment. At this moment, what is the altitude of the rocket, correct to one decimal place?
Thanks In Advance!
So far I have this, I am not quite sure where to take it from here! Thanks
