प्रश्न 6.
एक गाड़ी 2.4 लीटर पैट्रोल में 43.2 km की दूरी तय करती है। यह गाड़ी एक लीटर पैट्रोल में कितनी दूरी तय करेगी?
हल:
गाड़ी 2.4 लीटर पैट्रोल में दूरी तय करती है = 43.2 km
∴ 1 लीटर पैट्रोल में दूरी तय करेगी
= (43.2 ÷ 2.4) km
= \(\left(\frac{432}{10} \div \frac{24}{10}\right)\) km
= \(\left(\frac{432}{10} \times \frac{10}{24}\right)\) km
= \(\frac{432}{24}\) km
= 18 km
