5miles=8km how many miles is in 80km

50 miles

Step-by-step explanation:

Figuring this out is fairly simple, all you need to do is find out how many sets of 8 km are in 80km and multiply that number by 5. So you divide 80 by 8 and you get 10, then multiply 10 by 5 and you'll get 50. There are 50 miles in 80km.

19.79 ft

Step-by-step explanation:

Given data

We are given that the dimension of the room is

Length= 14ft

Width= 14ft

Required

The Diagonal of the room

Applying the Pythagoras theorem we have

D^2= L^2+W^2

substitute

D^2= 14^2+14^2

D^2= 196+196

D^2= 392

D= √392

D= 19.79 ft

Hence the distance from one corner to the other is 19.79 ft
