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

Answer:
The answer is
<h2>18</h2>
Step-by-step explanation:
a ∆ b = a² + ab + b²
(3 ∆ 2)
a = 3 b = 2
(3 ∆ 2) = 3² +3(2) + 2²
= 9 + 5 + 4
= 9 + 9
= 18
