Question

Will Give Brainliest! 50 PTS :)


In an 8.00 km race, one runner runs at a steady 12.0 km/h and another runs at 14.0 km/h .

How far from the finish line is the slower runner when the faster runner finishes the race?

Answer 1

The slower runner is farther from the finish line. 2.06 km

8 - 5.94 =2.06

Answer 2

-- Running at (14 km/hr), it takes the faster runner (8 km)/(14 km/hr) = 0.571 hr  to run the complete race.

-- In that time, the slower runner covers (12 km/hr) x (0.571 hr) = 6.857 km .

-- At that point, he still has (8 km - 6.857 km) = 1.143 km or 1143 meters left to go.
