Step-by-step explanation:
Convert to improper fractions:
4 1/2 = 9/2
1 1/2 = 3/2
Find the reciprocal:
9/2 / 3/2 = 9/2 x 2/3
Multiply:
9/2 x 2/3 = 18/6
Simplify:
18/6 = 3
Average acceleration: ( v - v o ) / Δ t
v = 0 m/s, v o = 20 m/s, Δ t = 3.5 s
a (average) = ( 0 m/s - 20 m/s )/3.5 s = - 20 m/s / 3.5 s =
= - 5.7142857 m/s² ≈ - 5.71 m/s²
67 ÷ 10 x 4 = 26.8 hours for her to eat 67 cookies
