Answer:
B) 7.94 × 10 8 miles
Step-by-step explanation:
Given
Distance between Earth and sun=E=9.3* 〖10〗^7 Miles
Distance Between Saturn and Sun=S=8.87* 〖10〗^8 Miles
In order to find the distance between Earth and Saturn, we have to subtract the distance between earth and sun from the distance between Saturn and sun. So
Distance between Earth and Saturn=S-E
=(8.87* 10^8 )-( 9.3* 10^7 )
As the distances are in scientific notation, to perform subtraction, the powers of 10 in both quantities have to be same, so
=(8.87*10* 10^7 )-(9.3* 10^7 )
=(88.7* 10^7 )-(9.3* 10^7)
=79.4* 10^7 Miles
It can also be written as:
Distance between Earth and Saturn=7.94* 10^8 Miles ..
