Example 2: A space probe is traveling at 50,000 meters per hour. How many times faster would it have to travel to
reach 10% of the speed of light?
Solution: In RPN mode, press:
¹ÜÏ10¯
Now convert the space probe's speed to meters per second.
50000Ï60¯60¯
Now compute the number of times faster the probe would have to travel to reach 10% of the speed of light
by dividing the two values.
