I believe the answer is <span>6,227,020,800</span>
Let the walker’s speed be W, then the biker’s is W+1.5W=2.5W. Difference in speed is 1.5W. Distance=speed times time, so 12.5=1.5W×1.5=2.25W, and W=12.5/2.25=1250/225=50/9=5.56 mph. The biker’s speed is 2.5W=125/9=13.89 mph to 2 Dec places.
(Note: “1.5 times faster than a walker’s speed” could not reasonably mean the biker’s speed=1.5W because this would give W=16.67 mph, which is very fast for a runner, let alone a walker (!), and a biker’s speed of 25mph.)
Answer:
z=-32
Step-by-step explanation:
5=z/-4 -3

-32=z
Answer:
y = -x - 8
Step-by-step explanation:
Slope intercept form is y = mx + b, so subtract x from both sides to convert the equation to slope-intercept form.
