Answer:49 sec
Step-by-step explanation:
Given
Maximum speed to reach is 183.58 mi/h
Length of course is 5 mi
acceleration rate is defined by 60mi/h in 4 sec
therefore acceleration(a)


To reach a speed of 183.58mi/h with an acceleration of 
Using equation of motion
v=u+at


t=0.00339 hours
t=12.23 s reach maximum speed
To complete course it takes


t=0.01360 hour
or 
60-3d + 20-6 =4d
74-3d =4d
-3d =4d -74
-7d = -74
D=74/7
Answer:
neither
Step-by-step explanation:
3-5w+12+2w-3
(3+12-3)=12
(-5w+2w)=-3w
-3w+12
1. -2<2 2. -4> -5. -20<20. -7>-8. -10<-1. 50>-100
