Mr. & Mrs. Martin drove 200 miles in September. They drove 2 times as many miles in November as they did in September. They drove 2 times as many miles in October as they did in November. How many miles did Mr. & Mrs. Martin drive in October?

800 miles

Step-by-step explanation:

Given that:

Total miles driven by Mr and Mrs. Martin's in September = 200 miles

Miles driven in November = 2 times the miles driven in September;

Hence, miles driven in November = (2 * 200) = 400 miles

Miles driven in October = 2 times the miles driven in November ;

Hence, miles driven in October = (2 * 400) = 800 miles
