He walked 3/8 of a mile this weekend. You multiply the numerator in 3/4 by the numerator in one half, and get a numerator of 3. You multiply the denominator of 3/4 by the denominator of 1/2, and get a denominator of 8
The required equation is y=8×(
Step-by-step explanation:
Given,
The two points are (1,2) and (0.5,4)
To find the exponential equation of these given points.
Formula
The general form of exponential equation is y =
where, A and B are any real number.

Now, the points satisfy the equation.
So,
2 =
------- (1) and
4 =
------ (2)
Now (1) ÷ (2) we get,
= 
or,
= 
or, b =
[ by squaring we get]
Now, from (1) we get,
2 = a×
or, a = 8
Hence,
The equation is y=8×(

Determine the arrival time
First, we calculate the time taken from Belfast to Dublin using:

Substitute values to the expression.

Cross Multiply



Arrival time is then calculated as:
