<u>Answer: </u><em>Nick</em>
<u>Step-by-step explanation: </u>
<em>Nick is the one who will go to bed first because he needs the most sleep. Nick needs 10 hours of sleep, then it would be Brad who needs 9 , then Will who needs 8</em>
Y=1x-90
-90 is the y-intercept and you get 1x because it rises 10 and runs 10.
10/10 is 1.
Answer:
1/9
Step-by-step explanation:
1/3 times 1/3 = 1/9
Answer:
exact form -40/3 decimal form -13.3 the 3 after the point would have a line over it because its repeating mixed number form -13 1/3
Step-by-step explanation:
The average speed of the student for his entire walk is equal to 1.5 m/s. Therefore, option (b) is correct.
What is the average speed?
The average speed of a body is calculated as the total distance traveled in a fixed interval of time. The average speed can be determined by dividing the total distance traveled by a body by the total time.
The average velocity is a single value if the object moves uniformly. Speed is a scalar quantity, it has no specified direction. The average speed has the S.I. unit the same as velocity i.e. m/s.
Given the distance covered by a student in first 80 sec = 100m
After stooping for 30sec again cover a distance of 200m in 90sec.
The total distance traveled by the student = 100 + 200 = 300m
The time taken by student to cover distance = 80 + 30 +90 = 200 sec
The average speed of the student = total distance/ total time taken
= 300/200 = 1.5 m/s
Therefore, the average speed of the student is equal to 1.5m/s.
