Step-by-step explanation:
so if the first man moves 30 km a days then after:
6 days he will be (6×30)km or 180 km away.
6+9 days he will be (15×30) km or 450 km away.
and the second man started moving on the sixth day and reached the first man on the 15 days which means he reached 450 km in 9 days. = 50 km per day. speed =50 ÷ 24=2.083 km/h
