Solving 5th-grade math on pages 60 and 61 VBT workbook 2, Velocity, problem 130
1. Solve Exercise 1 - Math workbook for 5th grade exercise book 2 page 60
Problem:
An automobile travels a distance of 120km in 2 hours. Calculate the speed of the car.
Solution Method
To calculate speed, we divide the distance by the time taken.
Speed formula: v = s : t
Answer:
The speed of the car is:
120 : 2 = 60 (km/hour)
Answer: 60 km/hour
2. Solve Exercise 2 - Math workbook for 5th grade exercise book 2 page 61
Problem:
A person walks a distance of 10.5 km in 2.5 hours. Calculate the walking speed of that person.
To find the speed, divide the distance by the time.
Speed formula: v = s : t
v = s : t
Answer:
The walking speed is:
10.5 : 2.5 = 4.2 (km/h)
Answer: 4.2 km/h
3. Solve problem 3 - Math workbook grade 5 exercise 2 page 61
To calculate speed, we divide the distance by the time:
73.5 : 1.75 = 42 (km/hour)
Answer: 42 km/hour
4. Solve problem 4 - Math exercise book grade 5 unit 2 page 61
Convert the time to decimal form with units in hours.
Calculate speed by dividing distance by time:
Speed formula: v = s : t
Answer:
The duration of the motorcycle journey is:
10:00 - 8:15 = 1 hour 45 minutes
1 hour 45 minutes = 1.75 hours
The speed of the motorcycle rider is:
The answer is:
42 km/hour
4. Solve problem 4 - Math exercise book grade 5 unit 2 page 61
Problem:
To solve the problem:
800 meters in 2 minutes 5 seconds
- Convert the time to seconds.
- Calculate speed by dividing distance by time.
Formula for velocity: v = s / t
Answer
Convert 2 minutes 5 seconds to 125 seconds
The speed of the athlete is:
800 divided by 125 equals 6.4 (m/s)
Answer: 6.4 m/s
