Answer:

Acceleration = 3m/s²

Step-by-step explanation:

Here ,

Initial velocity = 30km/h

Final velocity = 0km/h

Time = 10s

Acceleration = ?

We know ,

A = v-u/t

or , A = 0-30/10

or, A = 30/10

A = 3m/s²

Therefore the acceleration is 3m/s²

Store B:

24 bottles of water for $6.00

Then

48 bottles of water for $\$6.00\cdot 2=\$12$ (48 bottles is twice greater than 24 bottles)

$\$13.44-\$12=\$1.44$
