Answer:
v = 85/t
Step-by-step explanation:
Velocity is the change in displacement of a body with respect to time. It is expressed as
velocity = displacement/time
v = d/t
Given
d = 85km
t = t
Substitute tis parameters into the function;
v = 85/t
Hence the velocity v as a function of travel time t in hours is expressed as;
v = 85/t
Let A be the speed of hiker A and B the speed of hiker B.
let's say that B is faster than A, so B=A+0.5
we know that they met after 2 hours, and the distance each walked after 2 hours is given by:

One of the hikers travels at 4 miles per hour, the other one at 4.5 miles per hour
1.40 or 1.4 would be the square root of 2
Answer: the mean is -1.1
Step-by-step explanation: add up each number and divide the sum by 5 since there are 5 numbers in the table. (-32.6 + 24.7 + -8.3 + 19.1 + -8.4 = -5.5/5 = -1.1
Well,
1/5 of 1200 is 240
Then, you subtract 240 by 1200
So, you get $960
