Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
Answer:
14.6 minutes
Step-by-step explanation:
Since there is a 1 ms increase per day and there are 365 days a year, the time increase per year is 1 ms/day × 365 days/year = 365 ms/year.
So, in 24 centuries, there are 24 × 1 century = 24 × 100 years = 2400 years (since 1 century = 100 years)
So, the total of the daily increase in time in 24 centuries is time increase per year × 24 centuries
= 365 ms/year × 2400 years
= 876000 ms
= 876 s
= 876 s/60s
= 14.6 minutes

Answer:
a) 148.26 m
b) 21.94 degrees
Step-by-step explanation:
a)
tan 56 = 100/x
1.4826 = 100/x
x = 148.26
b)
148.26 + 100 = 248.26
tan y = 100/248.26
tan y = 0.4028
y = 21.94 degrees
