Each hour,
x makes b/6 bearings
y makes b/4 bearings
z makes b/3 bearings
Together, each hour, x, y and z together make
b/6+b/4+b/3=b(1/6+1/4+1/3)=b(2/12+3/12+4/12)=b(3/4)=3b/4 bearings.
Time to make b bearings =
b/(3b/4)=4/3 hours = 1 hour 20 minutes.
Answer:
Straight?
Step-by-step explanation:
I believe the answer is 1.343 x 10^5
685-85=600
1 year =12 months
12 multiply by 2 =24
600 divided by 24=25
answer=25
The answer is 2
Y2-Y1 / X2-X1
