Question 236033
Care one travels from point a to c (244 miles).
 Car two travels at 60 mph from point a to b(140 miles)and 50 mph from b to c (200 miles). 
If both cars arrive at point c at the same time, how fast did car one drive?
:
Find the time required for car two to go a to b to c
Time = dist/speed
:
total time = time at 60mph + time at 50mph
t = {{{140/60}}} + {{{200/50}}}
t = 2.33 + 4 
t = 6.33 hrs
:
Find the speed of car one to drive 244 mi in 6.33 hrs
s = {{{244/6.33}}}
s = 38.5 mph speed of car one
