City A and city B are 832 miles apart. A car leaves city B bound for city A at 44 mph. At the same time, another car leaves city A bound for city B at 60 mph. How long will it take them to meet?
Answer provided by our tutors
Let
d = 832 mi the distance
v1 = 44 mph the speed of the first car traveling from B to A
v2 = 60 mph the speed of the second car traveling from A to B
t = the time they need to meet
Since distance = speed*time and the cars are traveling one towards the other we have:
v1t + v2t = d
44t + 60t = 832

t = 8 hr
The cars will meed it 8 hours.
