test yourself! practice tool in 2015, the average distance from earth to the moon was about 3.74×10^5 km. the distance from earth to mars was about 9.25×10^7 km. how much farther is traveling from earth to mars than from earth to the moon? write your answer in scientific notation. □×□ km

Answer

Explanation:

Step1: Rewrite numbers in standard form

The distance from Earth to the moon $d_{moon}=3.74\times 10^{5}=374000$ km. The distance from Earth to Mars $d_{mars}=9.25\times 10^{7}=92500000$ km.

Step2: Calculate the difference

$d = d_{mars}-d_{moon}=92500000 - 374000=92126000$ km.

Step3: Convert the result to scientific - notation

$92126000 = 9.2126\times10^{7}$ km.

Answer:

$9.2126\times 10^{7}$
