Question

A boat moved 39 kilometers in 2 hours.

The boat moved [BLANK] meters per minute.
Fill in the blank above.

Answer 1

Answer: 325 meters / min

Explanation:

39km=39,000m

2hours= 120 minutes

speed = distance /time

39000/120 =325 meters/minute

Answer 2

Explanation:

Convert from km to m and from h to min

`39km((1000m)/(1km) )=39000m`

`2h((60min)/(1h))=120min`

We can use a simple rule of 3 here.

`(39000m)/(120min) =(xm)/(1min)`

325 m/min
