Question 362392
Sam is traveling north at 25 mph when Patty passes by in the opposite direction at 40 mph.  How long will it take for the distance between them to be 195 miles?
...
sam = 25mph
Patty = 40 mph
there are driving away
so speed = 25+40=65 mph
distance = 195 miles
t=d/r
t=195/65
t= 3hours
