Lab 1: Scientific Calculations

Question 1 Given that light travels at 2.9979e8 (that's 2.9979*108 in scientific notation) meters per second, figure out how fast light moves in miles per second. Then convert this to miles per hour.

jshell> 4*5
$1 ==> 20

jshell> int x = 5;
x ==> 5

jshell> int y = 4;
y ==> 4

jshell> x*y
$4 ==> 20
