IMO D:

Toms distance=6t

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............

Bingo.

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 !!
