C.	7 hrs 40 min	D.	7 hrs 37 min

Answer and Explanation

Answer:7 hrs 38*2/11 min

Explanation:
At 7 O’clock the M.H is 35 dots behind the H.H
It gains 55 dots in the hour
It will gain 35 dots in 35/55 of an hour
7/11 i.e. 60 × 7 / 11 min
38 2/11 min
Hence the M.H has caught up & will cross the H.H at 7 hrs 38 2/11 min
