Q41 2011, Speed, Time and Distance

If a bus travels 160 km in 4 hours and a train travels 320 km in 6 hours at uniform speeds, then what is the ratio of the distances travelled by them in one hour

यदि एक-समान गति से चलने पर एक बस 4 घंटे में 160 किमी दूरी तय करती है तथा एक रेलगाड़ी 5 घंटे में 320 किमी दूरी तय करती है, तो इनके द्वारा एक घंटे में तय की गई दूरियों में क्या अनुपात है ?

Explanation Please wait..

Take the ratio of both the speeds. First bus = 40 kmph, so 40 Kms in one hour. Second bus = 64 kmph, so 64 kms in one hour. Ratio = 40:64 = 5:8
