Question

A cyclist is moving with a speed of 10km per hour. How long will he take to travel a distance of 15000m?

Answer 1

Answer:

we know

1km=1000m

then,

15000m=15000/1000=15km

it takes 1h to travel 10km for him

then it takes ½hour or 30 minutes to travel 5km

5km =30 minutes

then for 15 km= 3×30 minutes

=90minutes or 1½hour
