one car is driving 12mph faster than car 2. there is a 30 minute time gap between the 2 cars. the 2 cars are 24 miles apart. how fast is car 1 going?
c1 = car one velocity
c2 = car two velocity
c1 = c2 + 12 mph
At 30 min time c2 is 24 m of c1.
So c2 is travelling at 24/30 mpm or 24/0.5 mph or 12 mph
c2 = 12 mph
so
c1 = c2 + 12 mph
c1 = 12 + 12
c1 = 24 mph ◄ Ans
