Answer 2

Option C is correct.

Explanation:

Distance already traveled by Ed
`=211` miles

Also, Ed is driving at a rate of 63 miles per hour.

Distance
`=` Speed × Time

Distance traveled by Ed in
`x` hours
`=63x`

Total distance traveled by Ed
`=211+63x`

Also, total distance traveled by Ed is
`638` miles.

Therefore,

`638=211+63x`

Option C is correct.
