Solution for Exercise 3 on pages 144 and 145 of Math 5 Workbook

Problem:
A horse races on a 15km track and finishes in 20 minutes. Calculate the speed of the horse with the unit of measurement being m/minute.

Solving Exercise 3 on pages 144 and 145 of Math 5 Workbook

Method 1: Convert the distance from kilometers to meters, then calculate the horse's running speed by dividing the distance covered by the time taken.
Method 2: Calculate the horse's running speed by dividing the distance covered by the time taken for that distance. Convert the result from km/h to m/minute.

Answer:
Method 1:
Convert: 15km = 15000m.
The horse's running speed is:
15000 : 20 = 750 (m/minute)

Method 2:
The horse's running speed is:
15 : 20 = 0.75 (km/minute)
0.75km/minute = 750 m/minute
Answer: 750 m/minute.
