25m/s to miles/h Can anyone solve it? With explanation if you can

Dimas [21]

25 meters per second x 60 seconds = 1500 meters per minute

1500 meters per minute x 60 minutes per hour = 90,000 meters per hour

90000/1609.34 = 55.92 miles per hour

round answer to either 55.9 or 56 mph depending on what you need.

Students in a class are asked to stand in ascending order according to their heights for the annual class photograph. Determine

horrorfan [7]

Answer:

The function in Python is as follows:

def heightChecker(heights):

expected = []

count = 0

for i in range(len(heights)):

expected.append(heights[i])

expected.sort()

for i in range(len(heights)):

if expected[i] != heights[i]:

count+=1

return count

Step-by-step explanation:

Required

Function to return the number of out of position students

See comment for complete question

This defines the function. It receives the heights as a parameter, from the main

def heightChecker(heights):

This initializes a list, (expected list)

expected = []

This initializes the count of out of position students

count = 0

This iterates through the original list

for i in range(len(heights)):

The list item is then appended to the expected list

expected.append(heights[i])

This sorts the expected list in ascending order

expected.sort()

This iterates through the original and the expected lists

for i in range(len(heights)):

If list elements at the same index are not the same, count is incremented by 1

if expected[i] != heights[i]:

count+=1

This returns count

return count
