Questions & Step-by-Step Solutions
A gardener can plant 100 trees in 5 hours. How many trees can he plant in 3 hours?
Step 1: Find out how many trees the gardener can plant in one hour. Divide the total number of trees (100) by the total hours (5). This gives you 100 trees / 5 hours = 20 trees per hour.
Step 2: Now, to find out how many trees he can plant in 3 hours, multiply the number of trees he can plant in one hour (20) by the number of hours (3). This gives you 20 trees/hour * 3 hours = 60 trees.
