Answer

Answer:

the first hour to the second hour

Explanation:

Step1: Calculate speed for each interval

Speed (=\frac{\text{Change in distance}}{\text{Change in time}})

First - hour to second - hour:

Change in distance (=34 - 12=22) miles, change in time (=2 - 1 = 1) hour. Speed (=\frac{22}{1}=22) miles per hour.

Second - hour to fourth - hour:

Change in distance (=70 - 34 = 36) miles, change in time (=4 - 2=2) hours. Speed (=\frac{36}{2}=18) miles per hour.

Fourth - hour to sixth - hour:

Change in distance (=104 - 70=34) miles, change in time (=6 - 4 = 2) hours. Speed (=\frac{34}{2}=17) miles per hour.

Sixth - hour to eighth - hour:

Change in distance (=146 - 104 = 42) miles, change in time (=8 - 6=2) hours. Speed (=\frac{42}{2}=21) miles per hour.

Step2: Compare the speeds

(22>21>18>17)
