namely how many times does ¼ go into 2, well that'd be 2 ÷ ¼,

6(3x + 4) + 5(12-x) simplifies to
D) 13x + 84
plane 1 travels 395 miles in 1 hour
plane 2 travels 422 miles in 1 hour
together, they travel (395+422) 817 miles in 1 hour
to have 2451 miles between then, they'd need to travel

so in 3 hours, they'll be 2451 miles apart
