Answer:
0.56 m/s
Step-by-step explanation:
The average speed of a body tells how fast is the body moving; it is calculated as:
v=\frac{d}{t}v=td
where
d is the distance covered
t is the time elapsed
In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:
d = 1 km = 1000 m
The time elapsed to cover this distance is:
t=30 min \cdot 60 =1800 st=30min⋅60=1800s
Therefore, Ben's average speed is:
v=\frac{1000}{1800}=0.56 m/sv=18001000=0.56m/s
Hope this helps
Answer:
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the lengths of the angles' opposite sides are <em>1-√3-2</em>.
If the long leg is 8, then the short one is 8/√3, or <em>8√3/3</em>.
Therefore, the hypotenuse, which is <em>double the short leg</em>, is 16√3/3.
