Two cities are exactly 100 km apart. Chug leaves city A driving 30 kmph and Joe leaves City B half an hour later at 60 kmph. Who will be closer to city A when they meet?
It's a tricky question When they meet they will be at the same distance from city A.
Chug will be closer to A
After 05 hrs the distance between them will be 100-30*0.5=85 km They will meet after 85/(30+60)=0.94 hr Chug will travel 15+0.94*30=43.2 km which is less than half of total distance which means he will be closer to city A.
