Answer: 37.5 acre
Step-by-step explanation: First, let's find out how much acre there would be if there were 3 parks. Since we know our basic multiplication, 1.25 x 3 is 3.75. Next, we need to find out what 12.5 x 3 is. When you multiply 12.5 x 3 you get 37.5.

Answer:
5 seconds
Step-by-step explanation:
Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...
time = distance/speed
time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s
That is, the rear part of each train will be at point A 5 seconds after the front part.
The rear parts will pass each other 5 seconds after the front parts meet.
