Final answer:
To find the midpoint between city A and city C, sum the distances and then divide by 2, resulting in 100 miles.
Step-by-step explanation:
The question involves calculating the midpoint between two locations in a straight driving path. The total distance from city A to city C is the sum of the distances from city A to town B and from town B to city C, which is 55 mi + 145 mi = 200 mi. To find the midpoint along this path, divide the total distance by 2, which gives us 200 mi / 2 = 100 mi. Therefore, you will reach the midpoint between city A and city C after driving 100 miles.
The distance from City A to Town B is 55 miles and the distance from Town B to City C is 145 miles.
To find the halfway point, we add the two distances together and divide by 2: (55 + 145) / 2 = 200 / 2 = 100 miles.
Therefore, after driving 100 miles, you will reach the midpoint between City A and City C.
