Distance travelled by train in x minutes is equal to 60fx feet as per given constant rate of f feet per second.
As given in the question,
Train travelled at a constant rate f feet per second
Let d be the distance travelled by train in x minutes
1 second =f feet
60 seconds = (60f) feet
1 minute = (60f) feet
x minutes = (60fx)feet
Therefore ,distance travelled by train in x minutes is equal to 60fx feet
as per given constant rate of f feet per second.

Answer:
Answer choice C
Step-by-step explanation:
Similarly to the previous problem, there are two possibilities. In the first possibility, the chance of picking a digit lower than 7 is 6/9 or 2/3, because there are 6 digits below 7 and 9 digits in total. In this scenario, the probability of the second digit being below 7 is 5/8, since one of the digits has already been taken. The probability here is 5/8*6/9=5/12. In the other scenario, the probability of picking a number higher than 7 is 3/9 or 1/3. In this scenario, the probability of picking below 7 for the second digit is 6/8 or 3/4, because one of the digits has not been taken. 3/9*6/8= 1/4. Adding these two together, you get 8/12=2/3, or answer choice C. Hope this helps!
