Answer:

$\red{\bold{c)\:12.5 km/hr}}$

Explanation:

$\orange{\bold{Question -}}$

A train travels a distance of 46km in 2 hours and then 29km in 4 hours. Calculate the average speed of the train.

$\green{\bold{<strong>Solution</strong><strong> </strong>‐}}$

we know that ,

$average \: speed \: = \frac{total \: distance \: travelled}{total \: time \: taken}$

Given , Train travels 46 km in 2 hours and 29 km in 4 hours .

⟹ $average \: speed = \frac{46 + 29}{2 + 4}$

⟹ $\frac{75}{6} = 12.5 \: km \: hr$

$\red{\bold{Hence , }}$

The average speed = 12.5 km/hr
