How does the decimal point move when multiplying 79.816×103?

It moves two places to the right

Step-by-step explanation:

Lets pretend we are multiplying my 100 instead of 103. That has two zeroes, so 79.816 would turn into 7981.6

If we did multiply by 103, the answer would be 8221.048, which is still two places to the right

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
