Guidance for solving exercise 2 on pages 144, 145 of Math textbook Grade 5
Problem:
A canoe travels from A to B at a speed of 12km/h. The canoe departs at 7:30 AM and arrives at B at 11:15 AM. Calculate the length of segment AB.
Solution Method:
- Step 1: Calculate the travel time of the canoe from A to B by subtracting the departure time from the arrival time, converting the result to hours.
- Step 2: Calculate the distance AB by multiplying the canoe's speed from A to B by the travel time from A to B.
Answer:
The travel time of the canoe from A to B is:
11 hours 15 minutes - 7 hours 30 minutes = 3 hours 45 minutes = 3.75 hours
The distance AB is:
12 x 3.75 = 45 (km)
Final Answer: 45km.
