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.\n□×□ km

Answer

Explanation:

Step1: Identify the values

The distance from Earth to Mars is $d_{1}=9.25\times 10^{7}$ km and the distance from Earth to the moon is $d_{2}=3.74\times 10^{5}$ km.

Step2: Rewrite the numbers with the same exponent

We rewrite $d_{2}=3.74\times 10^{5}=0.0374\times 10^{7}$ km.

Step3: Subtract the two distances

$d = d_{1}-d_{2}=(9.25 - 0.0374)\times 10^{7}$ km. $9.25-0.0374 = 9.2126$. So $d = 9.2126\times 10^{7}$ km.

Answer:

$9.2126\times 10^{7}$ km
