Answer:
THE DISTANCE OF SUB IS 5892480000000IN
1MI=63630 IN
930000000MI=93000000×63360 IN=589248000000IN
X=NUMBER OF FIREFLIES
X=0.4IN=5892480000000IN
X=58924800000000IN×0.4IN
X=147312000000000
B is the answer hope I help
If a=0, then the denominator is equal to 0. Since you cannot divide by zero, you are not allowed to do this.
