Going to do my best and give my first ever explanation.
D = R x T
Silvia D = 48 mph x (t + 3/4) ====> (Note: 45 mins is converted to 3/4 to respect the units)
Kal D = 55mph x (t)
Given they both travelled the same distance, let the 2 equations equal each other.
48t + 144/4 = 55t
36=7t
t=36/7
t= 5 hours and 1/7 hour
We know that 1/6 is 10 mins so 1/7 has to be slightly less than 10, therefore answer D 5 hours and 8 mins.

In 45 mins (= (45/60) hours), Sylvia covered D= S x T
D = (48x45)/60 = 36 miles
Now for Kal to catch up with Sylvia, we consider relative speed of the two persons.
Relative speed (moving in same direction), RS= Speed of Kal- Speed of Syl = 55-48 = 7 mph
Time taken by Kal to catch up with Sylvia, T = D/RS
T= 36/7 = 5 (1/7) hrs = 5 hours and 8 minutes
Option D
D = (48x45)/60 = 36 miles
Now for Kal to catch up with Sylvia, we consider relative speed of the two persons.
Relative speed (moving in same direction), RS= Speed of Kal- Speed of Syl = 55-48 = 7 mph
Time taken by Kal to catch up with Sylvia, T = D/RS
T= 36/7 = 5 (1/7) hrs = 5 hours and 8 minutes
Option D
