The Giants left San Francisco heading northeast at 210km/hr.
At the same time,The Patriots left Boston headed southwest traveling at 180km/hr.
After 8 hours both teams landed at the airport in Indianapolis at the same time, How far apart are Boston and San Francisco?
:
Let d = dist between S.F. and Boston
:
Write a distance equation; dist = speed * time
:
d = 8(210) + 8(180)
d = 1680 + 1440
d = 3120 km
