Question

maximum speed of train is 80 km per hour it takes time to call distance of 400 kilometres find the ratio of maximum speed to average sleed​

Answer 1

$\huge{\mathfrak{Solution:-}}$

According to question we use the formula of average speed,

$Average\;speed = \frac{total\;distance}{total\;time}$

$= \frac{400}{10}$

$= 40\;km/hr$

$The\;ratio\;of\;maximum\;speed\;to\;average\;speed=\frac{80}{40}=2$

$So,\;the\;ratio\;of\;maximum\;speed\;to\;average\;speed = 2:1.$
