Answer 1

> the first runner can beat the second runner

⚽ Question ⚽

• A runner can complete a 750 m race in two and a half minutes. Will he be able to beat another runner who runs at 17.95 km/hr?

⚽ Solution ⚽

• We are given that the first runner can complete a 750 m race in 2 minutes and 30 seconds or 150 seconds

•°• Speed of the first runner = 750/150 = 5 m/sec

• We convert this speed to km/hr by multiplying it by 18/5

•°• Speed of the first runner = 18 km/hr

• Also, we are given that the speed of the second runner is 17.95 km/hr

Therefore,

the first runner can beat the

second runner

• Speed = Distance/Time

• Time: seconds(s), minutes (min), hours (hr)

• Distance: (meters (m), kilometers (km), miles, feet

• Speed: m/s, km/hr

• To convert from km / hour to m / sec, we multiply by 5 / 18. So, 1 km / hour = 5 / 18 m / sec

• To convert from m / sec to km / hour, we multiply by 18 / 5. So, 1 m / sec = 18 / 5 km / hour = 3.6 km / hour

• 1 km/hr = 5/8 miles/hour

• 1 hour= 60 minutes= 60*60 seconds= 3600 seconds

• 1 mph = (1 x 1760) / (1 x 3600) = 22/45 yards/sec

Answer 2

Answer:

We are given that the first runner can complete a 750 m race in 2 minutes and 30 seconds or 150 seconds.

=> Speed of the first runner = 750 / 150 = 5 m / sec

We convert this speed to km / hr by multiplying it by 18/5.

=> Speed of the first runner = 18 km / hr

Also, we are given that the speed of the second runner is 17.95 km / hr.

Therefore, the first runner can beat the second runner.
