An airplane flew in a straight line into a headwind for 6 hours, covering 2,550 miles. It then flew in the exact opposite direction (with the headwind now a tailwind behind it) at the same engine speed for 3 hours, traveling an additional 1,725 miles. How fast would the plane have been flying (in mph) if there was no wind?

2550/2=1225 in 3 hours against wind
1725 in 3 hours with wind
1725+1225=3000 wind cancels itself out.

3000/2=1500
1500/3 hours= 500 in 1 hour
500mph with no wind at all
