Answer:
1/36
Step-by-step explanation:
Exponentiation: 1/6 ^ 2 = 12/62 = 1/36
2/3 because 60 is in a hour and if you take away the zeros in 60 and 40 you get 4/6 and then you can simplify to 2/3
This is the concept of algebra, speed is given by:
speed=(distance)/time
Average speed=[(speed A)+(speed B)]/2
suppose the speed at the second mile was x mph; thus the average speed was:
(30+x)/2=60
solving for x we get:
30+x=60*2
30+x=120
subtracting 30 from both sides we get:
x+30-30=120-30
x=90 mph
thus the speed at the second mile should be 90 miles per hour
This function has a straight line graph and thus has no limit on the range.
Answer:
29.25
Step-by-step explanation:
(8 x 2.25) + (9 x 1.25)
