Question

Answer please .....​

Answer 1

Answer:

45 min

Step-by-step explanation:

36 + 54 = 90

90 ÷ 2 = 45

therefor, the average speed of the train is 45 min

Answer 2

Answer:

Time = 1 hr =60

because it is written 36km/hr that why

Total distance = 36 + 54= 90

Total time = 60 +60 =120

average speed = distance / time

= 90/120 =3/4 m/sec

average velocity = displacement /time

= 0 / 120 = 0 m/sec
