Mary is on the swim team. each day she swims 850m . how many kilometers does she swim each day? be sure to include the correct unit in your answer.

This is a simple conversion from metres to kilo metres problem in which we should know how much metres is one kilo metre or how much kilo meters is one metres.

So in order to convert from metres to k m we just have to divide by 1000 as 1 km is equal to 1000 meters. Similarly for the other way round we have to multiply by 1000 as 1 metre is 0.001 km.

SO if Mary swims 850 metres each day then she swims around 0.85 km every day.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
