#"overall average speed" = 430 "miles/hour"#

Explanation:

The question asks for overall average speed, not velocity.
Therefore, the answer is merely

#"overall average speed" = "total distance"/"total time"#

#"overall average speed" = (1500 "miles")/(3.5 "hours") = 430 "miles/hour"#

I hope this helps,
Steve
