i don’t know the answer. Sorry

Answer 2

Step-by-step explanation:

first lets calculate the whole length of travel : L = (2×16) (3×6) = 50Kmand we know that this man traveled for t = 5 hours in all.so the average speed is : V = 50/5 = 10 Km/h again the same approach:L = 68 20 = 88 Kmt = (68/51) (20/40) = 1.83 hV = 88/1.83 = 48 Km/h
