Question

How much must be added to 750 metres to make 2 km​

Answer 1

you need to add 1250 to 750 in order to make 2 km

Explanation:

We know that:

1 KM = 1000 meters

and out of those 1000, we already have 750, therefore:

1000-750 = 250

Which completes 1 km now, since there are 2 km, add 1000 to 250:

1000+250 = 1250

So you need to add 1250 meters to make 2 km

Hope this helps!

Answer 2

1250 meters because 2 km is 2000 meters

2000 - 750

= 1250
