Question 1
A person travels at 39 km/h for 2 hours and then at 77 km/h for 2 hours. What is the average speed?
Step-by-step:
1. For equal time intervals, Average Speed = (v1 + v2) / 2
2. = (39 + 77) / 2 = 58.0 km/h
1. For equal time intervals, Average Speed = (v1 + v2) / 2
2. = (39 + 77) / 2 = 58.0 km/h
