Guidance on solving exercise 3 on page 21 of Math 5 workbook
Problem:
A team of 10 people can dig 35 meters of ditch in a day. If 20 more people join, how many meters of ditch can they dig in a day? (Each person digs the same amount).
Solution method:
- Step 1: Find the number of meters of ditch 20 people can dig in a day by multiplying the number of meters dug in a day by 20, then divide by 10.
- Step 2: To find the total number of meters of ditch dug in a day by the team, add the number of meters dug by the team of 10 people to the number of meters dug by the additional team of 20 people.
Answer:
In a day, 20 people dig:
35 x 20 / 10 = 70 (m)
In a day, the entire team digs:
35 + 70 = 105 (m)
Answer: 105 meters.
