Answer 1

3.6 kilometres
3600 metres
S=d÷t
3=d÷1200
3×1200=d
3600= d

Answer 2

Given - Time and speed

Find - Distance

Solution - The distance between school and house is 3600 metres or 3.6 kilometres

Firstly converting time in seconds.

As per the known facts, 1 minute = 60 seconds

20 minutes = 20*60

Performing multiplication -

20 minutes = 1200 seconds.

Finding distance using the formula -

Speed = distance/time

Distance = 3*1200

Performing multiplication -

Distance = 3600 metres

So, the distance between her house and school is 3600 metres or 3.6 kilometres
