How many minutes will it take the ant to reach the hole?

10 minutes

Step-by-step explanation:

Every minute: 40-10=30

300/30=10

Can i have brainliest?

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

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
