Part a is 216.4 just add all of the supplies cost together
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
![\frac{2451 miles}{817 miles}=3](https://tex.z-dn.net/?f=%5Cfrac%7B2451%20miles%7D%7B817%20miles%7D%3D3)
so in 3 hours, they'll be 2451 miles apart
