Answer:
64.6 km/h
Step-by-step explanation:
18:14 = 18h 14'
1h = 60'
18h = 17h + 60'
18h14' = 17h + 60' ´14' = 17h 74'
then:
17h 74'
-17h 22'
= 0h 52'
the train travelled 56km at 52 minutes
56km/52minutes
1 hour = 60 minutes
52 minutes = 52/60 = 0.86667 hours
then:
56km/52minutes = 56km/0.86667hours
= 64.615 km/hours
Answer:
<em>mean absolute deviation would be 2.75</em>
Step-by-step explanation:
mean: 4 + 2 + 2 + 10 = 18/4 = 4.5
4.5 - 4 = 0.5
4.5 - 2 = 2.5
4.5 - 2 = 2.5
4.5 - 10 = 5.5
mean absolute deviation: 0.5 + 2.5 + 2.5 + 5.5 = 11/4 = 2.75
~hope this helps~
