Question

Peter Saltwood can paint 140 doors in 7 hours, while Carl Kepler can paint 42 doors in 4 hours. Who can paint doors faster, Peter or Carl?

Answer 1

Hi , cherry hop u like my answer!
Simple division. 140/7 = 20. So Peter can do 20 doors an hour. 42/4 =10.5. So Carl can do 10.5 per hour. So obviously Peter can go faster.

hope that helps:)
