Answer:
it will take 1.4 hours for the two trains to be 294 miles apart
Step-by-step explanation:
Let t be the time taken for each train
The westbound train travels at 95 miles per hour.
Speed of westbound train = 95
time = t
Distance = speed * time = 95 t
The eastbound train travels at 115 miles per hour
Speed of eastbound train = 115
time = t
Distance = speed * time = 115 t
both trains are 294 miles apart means the distance between both trains are 294 miles
So we add the distance of both trains and set it equal to 294
95t + 115t = 294
210 t =294
t = 1.4
So, it will take 1.4 hours for the two trains to be 294 miles apart

I think the small coin makes 3 revolution
The probability that a girl will be selected from the class is 0.7
To get 75 using 7, 5, 6, and 3 only once:
= (7+5) * 6 + 3
parentheses first
= 12 * 6 + 3
multiplication before addition
= 72 + 3
= 75
Without being given any constraints, I'm assuming multiplication and addition were allowed.
Hope this helps! :)
