Question

Tom is cycling. He covers a distance of 100cm in one paddle. If Tom wants to cover 2.15km, how many times he has to paddle the bicycle?​

Answer 1

Dear student,

In 1 paddle, 
Tom covers a distance of 100 cm
We know, 1km=1000m1m=100cm
∴1 km=(1000×100) cm=100000 cm 
⇒2.15 km=215000 cm 
Number of paddles required=Total distancedistance covered in 100 cm=215000100 paddles =2150 paddles
Thus, he paddles 2150 times to cover 2.15 km
