a train covers a distance of 125 kilometres at a speed of 50 km per hour how much time does it take
Answers
Answer:
The whole sum is in the S.I. Unit:
Speed= 75km/hr
= m/s
= m/s
1) Time= 20 mins= 20×60 secs= 1200secs
Distance = Speed×Time
D= ×1200 metres
D= 25000 m= 25 km
2) Distance= 250km = (250×1000) metre, Speed=
Time=
T=12000secs= 3.33 hour
2.
Speed of trian = 75 km/hr = 75 km in 60 min
60 min - distance covered 75 km
20 min - distance covered = ?
i) Distance =
To cover a distance of 75 km it takes 60 min
to cover a distance of 250 km, how many min?

Answer:
2.5 h or 5/2 h
Step-by-step explanation:
Distance covered by train = 125 km
Speed of train = 50 km/h
Time taken by train = Distance/Speed
= 125/50 h
= 2.5h or 5/2h
1 hour = 60 minutes
5/2 hour = 5/2 × 60
= 5 × 30 min
= 150 min
1 minute = 60 s
150 minute = 60 × 150 s
= 9000s
