Answer:
4 inches per second
Step-by-step explanation:
Speed = distance/time
Given
Distance = 20 feet
12 inches = 1 foot
X inches = 20 feet
X = 20 x 12 = 240 inches
Time = 1 minute = 60 secs
Therefore
Speed = 240/60
= 4 inches per second
Answer:
15.5 feet

Given:
Patty is building a rope ladder tree house she needs two 4 foot pieces of rope for the sides of the ladder.
She needs 6 pieces of rope each 15 inches long for the steps.
Question asked:
How many feet of rope does patty need to make the ladder ?
Solution:
She needs for the sides of the ladder = Two 4 foot pieces of rope
= 2
4 feet = 8 feet
She needs for the steps of the ladder = 6 pieces of 15 inches long rope
= 6
15 inches = 90 inches
Convert 90 inches into feet:-

In this question, we would be examining the validity of some statements on the number π(pi)
π Is a whole number?
This is wrong, π is a fraction of 22 to 7 parts I.e 22/7
π Is double the radius?
This is wrong. It is the diameter that is double the radius
π Is approximately 3.14?
This is correct to an extent. The actual value in decimal is around 3.142857142857143 which makes the 3.14 somehow correct
π represents the ratio of the circumference of the circle to the diameter?
This is correct.
Mathematically, circumference C = π * diameter D
Hence C/D = π
π Is approximately 22/7?
This is correct. This is the ratio used for π
