You can put this solution on YOUR website! let the catchup distance be x
time taken by MIla is x/50
time taken by Husband = x/70
diffrenece in their starting time = 10 mins = 10/60 = 1/6 hours
time taken by Mila - time taken by husband = 1/6 hours
x/50 -x/70 =1/6
70x-50x= 70*50/6
20x= 70*50/6
x= (70*50)/(6*20)
x= 29.17
He will catch up after he drives 29.17 km.
