It might be A
Example: I tried to do the math and i came out with 1/20 so try it. i’m very sorry if it’s wrong
1 mile = 1.6 kms
22 miles / sec = 22*1.6 = 35.2 km / sec
Number of kms that Venus travel in 2 seconds = 70.4
The answer would be 30x-10
8 appears in the 10 thousand's place and is of 80,000 in value.
