Answer:
50 km/h
Step-by-step explanation:
Before the speed adjustments, their speeds were in the ratio 3:2. The difference in their speeds was 10 + 10 = 20 km/h, corresponding to a difference of 3-2 = 1 ratio unit.
Hence the faster car was traveling at 3×(20 km/h) = 60 km/h, and the slower car was traveling at 2×(20 km/h) = 40 km/h. After the speed adjustments, both cars are traveling at 50 km/h.
