I need to show how i got my answer.

anonymous · Answer

56 to 35

anonymous · Answer

5 miles-8 kilometres
1 mile - (8/5) km
35 miles -  (8/5)x 35 = 56 km

112km -  (5/8) x 112 = 70 miles

anonymous · Answer

or use a proportion 5/8 = 35/ x = 56

anonymous · Answer

and 5/8 = x/112

anonymous · Answer

Asgar.. Why is it's 112km - *(5/8)*? x 112 = 70 miles why not (8/5)?
