Decimal Places: Photofinish

The video tutorial discusses the preparation and competition of three top British sprinters: Linford Christie, Colin Jackson, and Michael Roswess, in a 60-meter sprint. It highlights the importance of precision in timing for short races, comparing it to marathon events. The race concludes with a photo finish, where Colin Jackson narrowly wins over Michael Roswess and Linford Christie, emphasizing the need for precise measurement in world-class sprints.

Which three British sprinters are preparing for a 60-meter race?

• Sebastian Coe, Roger Bannister, Steve Ovett

• Usain Bolt, Mo Farah, Steve Cram

• Paula Radcliffe, Jessica Ennis-Hill, Kelly Holmes

• Linford Christie, Colin Jackson, Michael Roswess

What is the main difference in timing precision between marathons and short sprints?

• Sprints are timed to the minute, marathons to the second

• Marathons are timed to the second, sprints to the hundredth of a second

• Marathons require timing to the minute, sprints to the second

• Both are timed to the nearest hour

How is a second divided to achieve more precise timing in sprints?

• Into milliseconds and microseconds

• Into minutes and hours

• Into tenths and hundredths

• Into halves and quarters

What was the result of the 60-meter race between the three sprinters?

• The race was canceled due to weather

• Michael Roswess and Linford Christie tied

• Colin Jackson won by a hundredth of a second

• Linford Christie won by a large margin

Why was a photo finish necessary in the race?

• To capture the athletes' expressions

• To verify the race distance

• To determine the winner due to a close finish

• To record the start of the race
