Apassenger plane travels about 7.97×10^2 feet per second. the plane takes 1.11×10^4 seconds to reach its detination. how far should the plane travel to arrive in their destination write in scientific notation

Comment
Just a reminder that scientific notation is written as a number between 1 and 10 and as 1 =<x < 10. You need to understand that because calculators quite frequently translate the number into an integer. 

Givens and formula
r = 7.97 * 10^2 feet per second.
t = 1.11 * 10^4 seconds.

The formula is d = r * t

Substitute and solve
d = r * t
d = 7.97 * 10^2 ft/second 
r  = 1.11 * 10 ^4 seconds and your units will be feet.

d = 7.97* 10 ^2 * 1.11 * 10^4
d = 8.85 * 10^6 feet. <<<<< answer
