Answer:
117mph
Step-by-step explanation:
Given that
Total number of stations= 3
Total average time of journey of train = 65
total stop time at three stations = 3×2 =6 min
Total distance between stops = 115 miles
as we can see
Total time train was travelling = 65- 6 =59 min
so, average speed of train can be calculated as:
Average Speed = 
Average Speed = 
To convert this speed into miles per hour (mph) multiply the above speed by 60
Average speed = 60×1.95 =117 mph
So the average speed of train is 117mph.
Answer:
Just to be on the safe side the first #1 is 31.5 and the second #1 is 57.82
Total cards = 52
Total red cards = 26
Total black cards = 26
P(one red and one black) = P(red and then black)+ P(black and then red)
P(one red and one black) =(26/52)(26/51) + (26/52)(26/51)
P(one red and one black) = 26/51 (Answer A)
