The cost of the milk is in 1950s.
Further explanation:
The price of milk in 2013 was around a gallon.
And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.
It is given that the price of milk in 2013 is a gallon.
Assume the price of milk in 1950 be a gallon.
Now, given that 8 times of is the price of milk in 2013.
Therefore, is the price of milk in 2013 and also
is the price of milk in 2013.
Equating and
equal as both are the price of milk in 2013 as,
Here, x is the price of milk in 1950.
Therefore, the cost of the milk is in 1950s.

The required, Mrs. Simpson's speed was 42 miles per hour.
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
To find the speed (or velocity) in miles per hour, we need to divide the distance traveled (in miles) by the time taken (in hours).
Mrs. Simpson drove 105 miles in 2 1/2 hours, which can be written as:
Time taken = 2.5 hours
Distance traveled = 105 miles
Speed = Distance / Time
Speed = 105 miles / 2.5 hours
To divide 105 by 2.5, we can convert the mixed number 2 1/2 to an improper fraction:
2 1/2 = 5/2
Then we can divide:
Speed = 105 miles / (5/2) hours
Speed = 105 miles * (2/5) hours
Speed = 42 miles/hour
Therefore, Mrs. Simpson's speed was 42 miles per hour.
