Guidelines for solving Exercise 2 on page 143 Mathematics Grade 5 textbook
Problem Statement:
a) On a distance of 23.1 km, a person rides a bike at a speed of 13.2 km/h. Calculate the person's travel time.
b) On a distance of 2.5 km, a person runs at a speed of 10 km/h. Calculate the person's running time.
Solution Method:
a) To calculate the travel time for biking, divide the distance by the biking speed.
b) To calculate the running time, divide the distance by the running speed.
Answers:
a) The travel time for biking is:
23.1 : 12.3 = 1.75 (hours) = 1 hour 45 minutes
b) The running time is:
2.5 : 10 = 0.25 (hours) = 15 minutes
Final Answers:
a) 1 hour 45 minutes;
b) 15 minutes.
