He had 33 whole sweets and 14 half-sweets.
Divide the miles and time to find the speed.
14.4/3 = 4.8
28.8/6 = 4.8
43.2/9 = 4.8
57.6/12 = 4.8
All the answers are the same, so therefore the speed is 4.8 mph.
Answer:
The correct option is;
10 m
Step-by-step explanation:
The parameters given are;
Height of the first pole = 20 m
Height of the second pole = 14 m
The angle the wire connected to their top makes with the horizontal = 30°
The vertical height subtended by the inclined wire, h = The difference in height between the two poles = 20 - 14 = 6 m.
Let the horizontal distance between the two poles = D
Therefore;
The horizontal length of the wire = D
From trigonometric ratios, we have;
Which gives;
The correct option is 10 m.
