Answer:
16 Km
Explanation:
multiply 30 by , the inverse of , to find the original distance
original distance = × 30 = 4 × 10 = 40 Km
Then
of distance = × 40 = 2 × 8 = 16 Km
2/5 of the distance between two places is 60km
assume 'x' is the distance between the two places..
3x/4 = 30
x = 120/3 = 40km
2(40)/5 = 16km
