Answer: 1.118x10^7
CHEMISTRY (conversion for miles/minute)
Step-by-step explanation:
Using conversions from meters - miles & seconds - minutes
2.998 x 10^8 m/s x 1 mi/1609m x 60s/1 min
using this equation the meters and seconds cancel out giving you miles per minute
After calculating you get 11179614, which you turn into scientific notation
This turns the problem into 1.1179614 BUT since the original equation has 4 sig figs, (2.998 is 4 sig figs) your final answer should have 4 sig figs
because you also moved the decimal 7 places to turn it into scientific notation, that will be the exponent in your final answer as well
so when you are computing your final answer, you take the first 4 digits (of 1.1179614) which is 1.118 (the 8 because you're rounding) and you finally have the equation
1.118 x 10^7 miles/minute
