Question

a train traveling at uniform speed take s 10hours to cover a distance of 1200km.express it's speed in m/s​

Answer 1

Answer:33,33m/s

Explanation:we first needed to covert km to meteres so 1200km ×1000m=1 200 000m, so now we have meter we need to find second per hout, so we need to convert hours to seconds 10hours × 3700s=36000s. So then we divide 1 200 000/ 36 000 so the answer is 33,33m/s

Answer 2

time =10 hour

distance =1200km

speed =( time/distance)

1 hour =60 min =60 multiply by 10

=600min

1200/600=2

hench, the speed of train is 2km
