The expression representing total number of juice boxes they bought is

Step-by-step explanation:

Given:

Number of 6-packages of juice bought by Jamar = 8

Number of 6-packages of juice bought by grandmother = 3

We need to write an expression which models Total number of juice boxes they bought.

Solution:

Let the Total number of juice boxes they bought be represented by 'y'.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
