You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 239 km south and 164 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM. If you are flying at a constant speed of 800 km/hr, how long after you depart JBLM will you be the closest to Mt. Rainier?

Seems easy?/
I've done this about 4 times..
And keep getting it wrong..
finally had to pick a different problem so it would change the numbers..
xD
Way to much work.
