Answer:
distance = 50 - (-150) = 50+150 = 200
Therefore, the distance between -150 and 50 is 200 units.
Please check the attached diagram below.
Step-by-step explanation:
Given the numbers
The number 50 is plotted 50 units to the right from position 0 on the number line, which is shown on the number line on the attached diagram below.
The number -150 is plotted 150 units to the left from position 0 on the number line, which is shown on the number line on the attached diagram below.
The distance between 50 and -150 can be calculated by subtracting -150 from 50.
i.e.
distance = 50 - (-150) = 50+150 = 200
Therefore, the distance between -150 and 50 is 200 units.

In any week, if you spent 13 hours a week, you'd be in the classroom for 46800 seconds .
Here, I have found the answer for you with an explanation:
Answer: Time at which the meet = 10:17:24 am
Step-by-step explanation: Speed of Ivan = 12 mph
Speed of Kate = 16 mph
Total distance traveled = Initial separation = 40 miles
Ivan leaves his house at 8:00 a.m and Kate leaves her house at 9:30 a.m
If t is the time of catch up after Ivan starting, time taken by Kate is t - 1.5,
We have
Distance = Speed x Time
Total distance traveled = Distance traveled by Kate + Distance traveled by Ivan
40 = t x 12 + (t-1.5) x 16
40 = 28t - 24
28t = 64
t = 2.29 hours
So after 2.29 hours of Ivan's starting they meet,
Time = 8:00 am + 2.29 hours = 10:00 am + 0.29 x 60 minutes = 10:17am + 0.4 x 60 seconds = 10:17:24 am
Time at which the meet = 10:17:24 am
The interpretation of the solution is that there are 15 true/false questions and 5 multiple choice questions.
