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:
domain: all real numbers
range: y<-2
Step-by-step explanation:
I think its correct but already know the answer sooo yea
A-b = 43----(1)
a+b = 13----(2)
(1)+(2) 2a=56
then a=56/2= 28
so b=13-28= -15
so that the numbers are -15 and 28
Answer:
we can calculate it by applying trigonometric ratios
