140 divided by 56, step by step

2.5

Step-by-step explanation:

For this, you can try to guess. 140 is too big for 56 to be multiplied by 2,and too small to be multiplied by 3. so 56 * 2 = 112, 140 - 112 = 28. 28 * 2 = 56, so 56 goes into 140 two and a half times.

Look up long division, and short division for it to be more in detail.

no this is a nonlinear negative

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
