How long does it take a jet engine traveling 1.6 x 10^7 kilometer per second to travel 5.3 x 10^14 kilometers?
:
Time = distance/speed
:
t = %285.3%2810%5E14%29%29%2F%281.6%2810%5E7%29%29 = 3.31%2810%5E%2814-7%29%29 = 3.31%2810%5E7%29 seconds

If the circumference of a very small circle is 2.35 x 10^-12 meter, then what is the diameter of the circle?
pi%2Ad = 2.35%2810%5E-12%29
:
d = 2.35%2810%5E-12%29%2Fpi
:
divide pi into 2.35
d = .7353%2810%5E-12%29 = 7.35%2810%5E-13%29
