Answer: she would catch up with Tom in 1 hour.
Step-by-step explanation:
Let t represent the time it will take for Mary to catch up with Tom.
Tom leaves his boat from a dock and travels at a rate of 25 miles per hour. 
Distance = speed × time
Distance travelled by Tom in t hours is 
25 × t = 25t
Ten minutes later, Mary leaves the same dock in her speedboat and heads after Tom. Converting 10 minutes to hours, it becomes 10/60 hour 
Time spent by Mary is (t - 10/60) hours. If she travels at a rate of 30 miles per hour, it means that the distance that she would travel in 
(t - 10/60) hours is 
30(t - 10/60) 
= 30t - 5
By the time she catches up with Tom, they would have covered the same distance. It means that 
25t = 30t - 5
30t - 25t = 5
5t = 5
t = 5/5 = 1 hour
