A car goes 15 km on a gallon of octane when it is driven at 50 km/h. When the car is driven at 60 km/h, it only goes 80% as far. How many gallons of octane are needed to travel 200 km if half the distance is traveled at 50 km/h and the rest 60 km/h?

Correct Answer: 15.00
প্রতিক্ষেত্র গতি ৫০ কিমি/ঘন্টায় দ্বিতীয় ক্ষেত্রে গতি ৬০ কিমি/ঘন্টায় প্রতি গ্যালন এ যায় = ১৫ × ৮০/১০০ = ১২ কিমি ৫০ কিমি/ঘন্টায়, ৫ কিমি যায় = ১ গ্যালন অকটেনে ২০০/২ = ১০০ কিমি যায় = ১০০/১৫ গ্যালন আবার, ৬০ কিমি/ঘন্টায় ১২ কিমি যায় = গ্যালন অকটেনে ১০০ কিমি যায় = ১০০/১২ গ্যলনে মোট যায় = ১০০/১৫ + ১০০/১২ = ৪০০ + ৫০০/৬০ = ৯০০/৬০ = ১৫ গ্যলন
