Jerry is running away from Tom, who is 5 meters behind, at a speed of 2.5 meters per second. To catch Jerry before he reaches his hiding spot that is 10 meters ahead, what must Tom's minimum speed be?
5 meters per second
3.75 meters per second
7.5 meters per second
1.25 meters per second

Ten meters ahead of Jerry I guess
How long will Jerry take to get there?
10 meters * 1 second / 2.5 meters = 4 seconds (pathetic speed :(
so
Tom must do 15 meters in 4 seconds
15 meters / 4 seconds = 3.75 meters / second
