Answer:
I b3live it is 50 miles/hour
Step-by-step explanation:
We need to know how many miles he drove from 9:00 to 10:30 so you do 150-75 which is 75. Then, you do 75÷1.5 because 9:00 and 10:30 are an hour and a half apart and then you get 50 mph.
The answer is: 
The explanation is shown below:
1. Cynthia rounds the number, which is identified as
, to one decimal place and the result is 6.3.
2. Based on this, we know that
could have been between 6.25 and 6.35. Therefore, the error interval for
is given by:

Where
indicates that the value 6.25 is included and
indicates that the value 6.35 is not included (Because if
had been exactly 6.35, Cynthia would round up to 6.4).

Step-by-step explanation:
Jonah's position range :
Between - 1 1/2 meters and - 2 1/3 meters with respect to sea level
With regards to sea level and the range of position given ; Jonah's position will be below sea level, that is Jonah's position cannot be a positive location on the number line, thus all options with positive values are incorrect.
Hence Jonah's position will be any number on a number line located in between :
-2 1/3 and - 1 1/2
That is
-2 1/3 ≤ Jonah's location ≤ - 1 1/2
-2 1/2 ( this is less than - 2 1/3) (incorrect)
-1 5/6 lies in between the given range and is thus a possible position.
