Car A travels at the speed of 65 km/hr and reaches its destination in 8 hours. Car B travels at the speed of 70 km/hr and reaches its destination in 4 hours. What is the ratio of the distance covered by car A and car B respectively?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 13 : 7
Each car’s distance is its speed multiplied by its travel time; the two distances are then compared as a ratio and reduced to its lowest terms.
Car A covers \(65\times8=520\) km
Car B covers \(70\times4=280\) km, a shorter trip at a higher speed
\(520:280=13:7\), dividing both by their common factor 40
