The slope of y=9x is 9/1 which simplifies to 9
The slope of y=10x-2 is 10/1 which simplifies to 10
Answer:
70 clicks in 20 seconds
Step-by-step explanation:
The speed of the train in mile per hour is approximately the number of clicks heads in 20 seconds.
Each click shows that the train has travelled 30ft
1 click per second is =(30ft/sec = 3600 × 30) / 5280
20.45mph approximately 20mph
Therefore
20mph = 20 clicks in 20 s
30mph = 30 clicks in 20s
70mph= 70 clicks in 20s
Answer:
5 s + (3 * 13) + 20 = 7 * 12
