Solving 5th-grade math on pages 50 and 51 of VBT workbook 2, Time Measurement addition, Exercise 123
1. Solve Exercise 1 - Math workbook for 5th grade, page 50
Problem Statement:
Calculate
4 years 3 months + 3 years 7 months
3 days 14 hours + 5 days 6 hours
5 years 7 months + 2 years 9 months
12 days 6 hours + 15 days 21 hours
23 hours 15 minutes + 8 hours 32 minutes
13 minutes 35 seconds + 3 minutes 55 seconds
Solution Method:
- Arrange the quantities in a straight line and perform the calculation as with the addition of natural numbers.
- After each calculation, record the corresponding measurement unit.
- If the time measurement in the smaller unit can be converted to a larger unit, perform the conversion to the larger unit.
Answer:
4 years 3 months + 3 years 7 months
= 7 years 10 months
3 days 14 hours + 5 days 6 hours
= 8 days 20 hours
23 hours 15 minutes + 8 hours 32 minutes
= 31 hours 47 minutes
5 years 7 months + 2 years 9 months
= 7 years 16 months or 8 years 4 months
12 days 6 hours + 15 days 21 hours
= 27 days 27 hours or 28 days 3 hours
13 minutes 35 seconds + 3 minutes 55 seconds
= 17 minutes 30 seconds or 16 minutes 90 seconds
2. Solve Exercise 2 - Math workbook for 5th grade, page 51
Challenge:
Set up the calculation and compute:
a) Add 7 years 5 months to 3 years 7 months
b) Sum 12 hours 27 minutes and 5 hours 46 minutes
c) Combine 6 days 15 hours with 8 days 9 hours
d) Calculate 8 minutes 23 seconds plus 8 minutes 52 seconds
Method of Solution
- Arrange the numbers in a straight line and perform the calculation as in the addition of natural numbers.
- After each calculation, record the corresponding measurement unit.
- If the time measurement in the smaller unit can be converted to a larger unit, perform the conversion to the larger unit.
Answer
3. Solve Problem 3 - Math workbook for 5th grade, page 51
The Challenge:
In a marathon race, athlete An completes the entire distance in 2 hours and 30 minutes. Athlete Ba finishes 12 minutes after athlete An. How much time does athlete Ba take to complete the entire distance?
Method
To calculate the time athlete Ba takes to complete the entire distance, add the time athlete An takes with 12 minutes.
Answer
Athlete Ba takes the entire distance in:
2 hours 30 minutes + 12 minutes = 2 hours 42 minutes
Answer: 2 hours 42 minutes.
