Answer:
C. 1 mile per minute.
Step-by-step explanation:
By proportion, 60 miles per hour = 1 mile per 1/60 of an hour.
1/60 hour = 1 minute.
<h3>
Answer: -2/3</h3>
==================================================
Explanation:
Use the slope formula to find the slope of line E
m = (y2-y1)/(x2-x1)
m = (10-8)/(4-7)
m = 2/(-3)
m = -2/3
The slope of line E is -2/3
The slope of line F is also -2/3 since parallel lines have equal slopes but different y intercepts.
Answer: 2.4 cm
Step-by-step explanation:
1.5 divided by 250 gives that each page is .006cm. 400 times .006 is 2.4cm
Answer:
x<7
Step-by-step explanation:
12x>9(2x-3)-15
12x>18x-27-15
12x>18x-42
-6x>-42
x<7
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.)
