Question 1199766: One speed skater starts across a frozen lakebat an average speed of 8 m / s. Ten minutes later, a second skater start from the same points and skate the same direction at speed of 9m/s. How many seconds after the 2 and skater will overtake the first skater?

In 10 minutes at 8 m/s, the first skater travels (10)(60)(8) = 4800 m.
The rate at which the second skater catches up to the first is the difference in their speeds, which is 1 m/s.
To make up the 4800 m at the rate of 1 m/s takes 4800/1 = 4800 seconds.
ANSWER: 4800 seconds

(1) That's a very long frozen lake
(2) Speed skaters don't maintain speeds like that for those amounts of time
