When solving average speed, Add all the given km/h and then divide it by the total of the given numbers. For example, the given are 120 km/h and 67 km/h. Add it all and divide its sum by 2 because the total numbers of the given km/h is 2. Now, let us solve the problem!
Solution:
Item no. 1
S = 120km/h+67km/h
2
120 + 67 = 187km/h
Since the given km/h is 2, we will divide it by 2.
187 ÷ 2 = 93.5km/h
Therefore, the average speed for the trip is 93.5km/h
Answers & Comments
Answer:
1. 93.5 km/h is the average speed for the trip.
2. 72.5 km/h is the average speed.

S = 120 km/h + 67 km/h
2
120 + 67 = 187 km/h
Since the given km/h is 2, we will divide it by 2.
187 ÷ 2 = 93.5 km/h
Therefore, the average speed for the trip is 93.5 km/h

Item no. 2
S =- 65 km/h + 80 km/h
2
65 + 80 = 145 km/h
Since the given km/h is 2, we will divide it by 2.
145 ÷ 2 = 72.5 km/h
Therefore, the average speed is 72.5 km/h.
