Question

Miguel Lara, a Rarámuri from Copper Canyon in Mexico runs a 50km race in a time of 5:05.39 If the race starts at the plaza and continues through the Copper Canyon arriving back at the starting point in the plaza, what is Miguel Lara's velocity?

Answer 1

Total path length of race = 50 km

Time taken to complete the race = 5 hour 5 min 39 s

total time is given as = (5 * 60 * 60) + (5 * 60) + 39 s

$T = 18339 s$

now we know that speed is given as ratio of distance and time

$v = \frac{distance}{time}$

$v = \frac{50* 1000}{18339}$

$v = \frac{50000}{18339}$

$v = 2.73 m/s$

So the speed for the above motion is 2.73 m/s
