The round trip flight took 3.9 h flying time. the plane traveled the 510 mi to the city at 255 mi/h with no wind. how strong was the wind on the return flight? was the wind a head or tail wind?

Pleasse me i need an answer. give me the correct answer. answer if you know it ! the club will base its decision about whether to increase the budget for the indoor rock climbing facility on the analysis of its usage. the decision to increase the budget will depend on whether members are using the indoor facility at least two times a week. use the best measure of center for both data sets to determine whether the club should increase the budget. assume there are four weeks in a month. if you think the data is inconclusive, explain why.
