linda's distnce = 2(t+1)
they are equal
so t comes out to be 30 mins or 1/2
when tom will cover twice the difference....
6t= 2 *2(t+1)
t= 120 mins or 2 hours
thus differnce between bot the t's would be 90 mins or 3/2 hours...
Pls correct me if i wrong............
Tom starts when Linda is 2 miles away. Tom's speed is 6mph. Therefore, in 30 mins, both will be 3 miles apart frm A. (Same Distance)
After 120 mins(2 hours), Tom would have covered double the distance of Linda.
Positive Difference : 120-30 = 90 !!
GMAT offended me. Now, its my turn!
Will do anything for Kudos! Please feel free to give one.
