A train travelled at a constant speed of 40m/s
for a distance of 180000m
calculate the time taken for
the journey

Time = distance /  speed

Time = 180,000 meters / 40 m/s

Time = 4,500 seconds

1 minute = 60 seconds:

4,500 seconds / 60 seconds/minute = 75 minutes

1 hour = 60 minutes

75 - 60 = 15

The train traveled for 1 hour and 15 minutes.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
