Solution for Exercise 3 on page 144 of Math Grade 5 textbook
Problem:
A horse travels a distance of 15.75km in 1 hour and 45 minutes. Calculate the speed of the horse in m/minute.
Solving Method:
- Convert the length unit from km to meters; time unit to minutes.
To find the horse's speed, divide the distance the horse travels by the time it takes to cover that distance.
Answer:
Conversion: 15.75km = 15750m; 1 hour 45 minutes = 105 minutes.
The horse's speed is:
15750 : 105 = 150 (m/phút)
Answer: 150m/phút.
