Question

A train is travelling due east at an average speed of 120km/h.How far does this train travel in 6second?

Answer 1

Answer:

200m or 0.2km

Explanation:

We know Speed =distance *time

so,distance =Speed/time

• Speed =120km/hr
• time is 6s =6/3600
• as we know in 1hr there is 60*60s

so ,

distance=120*6/3600

=0.2km

Answer 2

Answer:

~180m

Explanation:

speed of train in one hour = 120

60 second is equal to 1

60 minute equal to 3600 second

120 kilometre is = 1,20,000

average speed is equal to distance / time

1,20,000 / 3600

now cancel zero

1200/36

approximately= 100/3~30

30 m/s *6s

~180 m
