The mean or average speed of a mobile moving north is: <u>Vprom= 20.575 m/sec</u>
The average speed of a series of given speed values is calculated by <u>summing</u> each of the <u>speeds</u> and then <u>dividing</u> by the number of speeds , as follows:
Speeds:
V1=18.5m/s
V2=22m/s
V3=20.3m/s
V4=21.5m/s
V avg =?
Average V = ( V1+V2+V3 +V4)/4
Vavg = (18.5m/s + 22m/s +20.3m/s + 21.5m/s)/4
Vavg = 20.575nm/sec

Answer:
The flea treatment is $2.05 cheaper at Pet Store 1.
Step-by-step explanation:
Pet store 1
Regular price = $33
40% off the regular price
= 40% of $33
= 0.4 × 33
= $13.2
25% off the regular price
= 25% of $33
= 0.25 × 33
= $8.25
Total paid = $33 - $13.2 - $8.25
= $11.55
Pet store 2
Regular price = $34
55% off of the regular price
= 55% of $34
= 0.55 × 34
= $18.7
5% off of the regular price
= 5% of $34
= 0.05 × 34
= $1.7
Total paid = $34 - $18.7 - $1.7
= $13.6
Difference in price = $13.6 - $11.55
= $2.05
The flea treatment is $2.05 cheaper at Pet Store 1.
