Ravi goes to school at a speed of 5 km/h and returns home at 3 km/h. If the total time taken is 2 hours, what is the distance between his home and school?
2.75 km
3.25 km
3.75 km
4.25 km
Answer: C
Let the one-way distance be d km. Then \(\frac{d}{5}+\frac{d}{3}=2\). Therefore, \(\frac{8d}{15}=2\), so d = 30 ÷ 8 = 3.75 km.
रवि 5 km/h की गति से स्कूल जाता है और 3 km/h की गति से घर लौटता है। यदि उसे कुल 2 hours का समय लगता है, तो उसके घर और स्कूल के बीच की दूरी कितनी है?
2.75 km
3.25 km
3.75 km
4.25 km
उत्तर: C
एक तरफ की दूरी d km मान लें। तब \(\frac{d}{5}+\frac{d}{3}=2\)। इसलिए \(\frac{8d}{15}=2\), जिससे d = 30 ÷ 8 = 3.75 km।
