Question

a train travels a distance of 60 km per hour for 0.52 hour at 30 km/hr for the next 0.24 and then at 70 KM/hr for the next 0.71 hour what is the average speed of train?​

Answer 1

$\sf\Large{\underbrace{Answer \implies 59.9\:Km\:per\:Hr.}}$

$\sf\large{\underline{\underline{Given:}}}$

$\sf\large{ \: \: \: Total\:Time = 1.47\:Hour}$

$\sf\large{ \: \: \: Total\:Distance\:Covered= 88.1\:Km}$

$\sf\large{\underline{\underline{To\:Find:}}}$

$\sf\large{ \: \: \: Average\:speed = ?}$

$\sf\large{\underline{\underline{Solution:}}}$

$\sf\large{Average\:Speed = \dfrac{Total\:distance\:travelled}{Total\:time\:taken}}$

$\sf\large{\implies Average\:Speed = \dfrac{88.1}{1.47}}$

$\sf\large{\implies Average\:speed= 59.9\:Km\:per\:hr}$
