A man travelled a distance of 150 km in 18 hours. He travelled partly on foot at 5 km/h and partly on bicycle at 10 km/h. What is the distance travelled on bicycle ?
Answer & explanation
Correct answer: option 1
Let distance traveled on bicycle = B km
So , Distance covered on foot = (150 - B ) km
According to question ,
\(\frac{B}{10}\) + \(\frac{150 - B }{5}\) = 18
\(\frac{B + 300 - 2B }{10}\) = 18
B = 120 km
So , Distance covered by bicycle is 120 km
