Question

A train travel 1000km 400 m 31hours 30 minuts what is the avrege

Answer 1

try to write your question properly so other can answer

anyways here is it :

average speed = distance/time

distance = 1004 km

time = 31.5 hr

average speed = 1004/31.5

= 31.873 km /hr

hopefully it's right if not sorry to waste time

Answer 2

Step-by-step explanation:

Average speed=Total distance covered/Total time taken

Therefore, Average speed=(1000km+400m)/(31 hrs+30 min)

=1km=1000m

=1000km=1000000m

And ,

1 hr=60min

31 hrs=1860 mins.

So, Average speed=1000000+400/1860+30

=1000400/1890

=53.12169312169312

OR

=5

$53 \times \frac{230}{1890}$
