Answer:
C
Step-by-step explanation:
The average speed can be obtained by adding the distances together and dividing by the total amount of time.
The total distance the man traveled from A to D is the addition of the distance from A to B plus the distance from B to C plus the distance from C to D. This is mathematically equal to 145 + 160 + 115 = 420 miles.
Dividing 420 miles by 6 = 70 miles per hour
