Step-by-step guide to solve Exercise 4 on Page 68 of the 5th-grade Math workbook
Problem:
In 3 hours, a motorcycle covers 93 km. In 2 hours, a car covers 103 km. How many more kilometers does the car cover than the motorcycle each hour?
Solution Method:
- Step 1: Calculate the distance the motorcycle travels in 1 hour by dividing the total distance in 3 hours by 3
- Step 2: Calculate the distance the car travels in 1 hour by dividing the total distance in 2 hours by 2
- Step 3: To find out how much more kilometers the car covers than the motorcycle each hour, subtract the distance the motorcycle covers in 1 hour from the distance the car covers in 1 hour.
Answer:
The motorcycle covers kilometers per hour:
93 : 3 = 31 (km)
The car covers kilometers per hour:
103 : 2 = 51.5 (km)
The car covers more kilometers than the motorcycle per hour:
51.5 - 31 = 20.5 (km)
Answer: 20.5km.
