Question

a tarin travles a distance of 1000 km 400 m in 15- 1/2 hours 30 min what is the average speed of the train.
​

Answer 1

Heya, buddy !!

Total distance distance in metres=1000+0.400

= 1000.4km

Total time taken = 18 hrs 30 min =18.5 hrs.

Average speed = 1000.4/18.5=54.076 km \hr.

Formula used :

$\underline \color{red} \small\boxed{average \: speed = \frac{total \: distance}{total \: time \: }}$

Hope it's helps ^-^
