एक बस और एक कार की चालों का अनुपात 7 : 11 हैं यदि कार 396 km की दूरी 6 घंटे में तय करती हैं, तो बस की चाल km/h में ज्ञात कीजिए|
Detailed Solution & Logic
Correct Answer:
42
Step 1: Find speed of the car
Car covers 396 km in 6 hours
Speed of car = 396 ÷ 6 = 66 km/h
Step 2: Use the ratio
Speeds of bus : car = 7 : 11
So,
Bus speed = \(\frac{7}{11}\times 66\)
= 7 × 6
= 42 km/h
✅ Final Answer: 42 km/h
Correct option: 42
