do you want an expression?
if so it would be T = 40 + 20h
t = total
h = hour(s)
Answer:
a) Josef jogging from A to B;
i. speed = 2 m/s
ii. velocity = 2m/s
a) a) Josef jogging from A to C;
speed = 1.9 m/s
ii. velocity = 2.2 m/s
Step-by-step explanation:
One major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.
a) Josef jogging from A to B;
distance = 300 m
time = 2.5 seconds = 150 seconds
i. his average speed = 
= 
= 2 m/s
ii. his average velocity = 
= 
= 2 m/s
b) Josef jogging from A to C,
distance = 300 + 100 = 400 m
time = 2.5 + 1 = 3.5 minutes
= 210 seconds
i. his average speed = 
= 
= 1.9 m/s
ii. his average velocity = 
= 4 m/s
= 1.9 m/s
his average velocity = 
= 2.2 m/s
X=112
Y=90
Explanation: Y is 90 because you can see that it is a right angle! To find X you can find the 3rd angle that is in the triangle with Y in it (which is 68) and then because X is supplementary to that angle we just found you can do 180-68 which is 112!
Answer:
Step-by-step explanation:
the slope of line n is also -3 as it is parallel to m
The answer is A
