To find the speed you must write S= d/t so for the first one we will chang 15 m to b so it is = 0.25h so s=3/0.25h = 12km/h an why secand is 45 m to h = 0.75h so S=d/t S =12/0.75 =16 km/h the to find the totel speed we should + the speed together so 12 + 16 = 28 km/h

Step-by-step explanation:
Answer:
y = 0
Step-by-step explanation:
Given (-5, 0) and (0, 0),
Find the slope (m):

Slope (m) = 0.
Find the y-intercept (b):
y-intercept (b) = 0. This is the value of y, when x = 0.
To write the equation of the line, substitute m = 0, and b = 0 into y = mx + b
y = (0)(x) + 0
y = 0 + 0
y = 0
Answer:
B
Step-by-step explanation:
Because 16 + 2.50 is less than 25 + 0.25x
