Answer:
512.4 miles
Step-by-step explanation:
The distance from city to beach town = 500 miles
Distance from airport to hotel = 20 kilometers
In order to find the total distance we have to convert the kilometers in miles to bring both quantities in same unit
So,
1 kilometer = 0.62 miles
20 kilometers = 20*0.62 =12.4 miles
As both the quantities are in same unit,
The total distance = Distance from city to beach town + distance from airport to hotel
= 500 + 12.4
= 512.4 miles
Hence, total distance covered by them is 512.4 miles ..
