and reaches ivaibur of 22:05 hours. Find the sheed
of the train if the distance between these places is
142 km.​

Answer 1

Answer:

0.32 m / min

Step-by-step explanation:

Distance = 142 km

Time = 22:05 - 14:45

22 hours can be written as 21 hours 60 minutes

22 : 05 can be written as 21 hours (60 + 05) minutes = 21 hours 65 minutes

So, TIme = 21 hours 65 minutes - 14 hours 45 minutes

= (21 - 14) hours (65 - 45 ) minutes

= 7 hours 20 minutes

1 hour = 60 minutes

7 hours = 7 * 60 = 420 minutes

7 hours 20 minutes = 420 + 20 = 440 minutes

Speed = Distance ÷ Time

= 142 ÷ 440

= 0.32 m / min
