Answer:
Sally's km/h during the first half hour is 7 .
<em>The lowest average speed is between the 3rd and 4th stops.</em>
Step-by-step explanation:
On the table during the first half hour, Sally traveled 7 km.
From the first stop to the second stop, she traveled 8 km; from the second stop to the third stop, she traveled 6 km; from the third stop to the fourth stop, she traveled 3 km; from the fourth stop to the fifth stop, she traveled 4 km; and from the fifth stop to the sixth stop she traveled 8 km. Therefore The lowest average speed is between the 3rd and 4th stops.

Answer:
0.25 or 1/4
Step-by-step explanation:
2 x 1 1/4 = 2 x 1.25 = 2.5 or 2 1/2
2.5 divided by 10 = 1/4 or 0.25
I don't know what your looking for, so be more specific, but I'm assuming your solving for x, so that's would be
x = -1
159 times in 3 seconds = 159/3 = 53 times per second <==
