1 answer:
Answer:
<h2>The answer is </h2><h2>B. 1/12</h2>Step-by-step explanation:
step one:
From the problem state, we can actually conclude that Jamie wants to share the half sheet of cake among her 6 friends
step two:
we can express this problem mathematically as
we can inverse the denominator and use a multiplication sign instead
multiplying both denominators we have
The answer is B 1/12

Answer:
1.76m/s ; 1.76m/s ; 1.74m/s, 0.86m/s
Step-by-step explanation:
Given the following :
Distance jogged in first direction (A to B) = 300m
Time taken = 2 minutes 50s = (2*60) + 50 = 120 + 50 = 170s
Distance jogged in opposite direction (B to C) = 100m
Time taken = 1minute = 60s
Recall:
Speed = distance / time
Therefore Average speed from A to B
Average speed = 300m/ 170s = 1.764 = 1.76m/s
Average Velocity = Displacement / time
Displacement = 300m ; time = 170s
= 300m / 170s = 1.76m/s
Average speed (A to C)
Therefore, average speed = total distance / total time taken
Total distance = (300 + 100)m = 400m
Total time taken = (170 + 60)s = 230s
Average speed = 400m / 230s
= 1.739m/s = 1.74m/s
Average velocity:
Displacement = distance between initials position and final position.
Initial distance covered = 300m. Then 100m was jogged in the opposite direction.
Distance between starting and ending positions, becomes : (300 - 100)m = 200m
200 / 230 = 0.87m/s
