1.	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» $\huge{\mathfrak{Solution:-}}$ ACCORDING to question we use the formula of AVERAGE speed, $Average\;speed = \frac{total\;distance}{total\;time}$ $= \frac{400}{10}$ $= 40\;km/hr$ $The\;ratio\;of\;maximum\;speed\;to\;average\;speed=\frac{80}{40}=2$ $So,\;the\;ratio\;of\;maximum\;speed\;to\;average\;speed = 2:1.$
