Answer:
25m/s
Step-by-step explanation:
distance = 30km = 30× 1000m
time = 20 min = 20 × 60 = 1200sec
we know,
speed = distance/time taken
= 30000/1200
= 25m/s

Answer:
25.12 meters
Step-by-step explanation:
The circumference of a circle is given by
(1)
where:

r is the radius of the circle
In this problem, the parachute has a diameter of 8 meters:
d = 8 m
The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

And therefore, by applying eq.(1) we can find the circumference of the circle:

2 2/3 x 3/11
= 8/4 x 3/11
= 24/44
Simplified
6/11
