Plug the given values into the R × T = D formula. The rate is 2.5 million feet per day and the distance is 10.2 million feet. Thus: 2.6 million × T = 10.2 million → T =

10.2‌million

2.6‌million

= approximately 4 days. Now, convert days to seconds. 1 day = 24 hours = 60(24) minutes = 60(60)(24) seconds = 86,400 seconds. So, the number of seconds in 4 days is 86,400 × 4 = 345,600 seconds. The closest answer is 350,000.
