two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per hour. The westbound train travels at 105 miles per hour. How long will it take for the two trains to be 320 miles apart? Do not do any rounding.

  1.6 hours

Step-by-step explanation:

Their separation speed is 95 +105 = 200 miles per hour. The time required for the given distance is ...

  time = distance/speed

  time = (320 mi)/(200 mi/h) = 1.6 h

It will take 1.6 hours for the trains to be 320 miles apart.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

no solution
