the winner in a recent Los Angeles marathon ran the 26-mile race in 2.23 hours. How many yards per minute did he run? Round to the nearest hundredth

Respuesta :

Distance = 26 miles

Time = 2.23 hours

1 mile = 1760 yards

26 m = 26 x 1760 = 45760 yards

1 hours = 60 minutes

2.23 h = 2.23 x 60 = 133.8 minutes

Speed rate = distance / time

Replacing:

S = 45760 y / 133.8 m = 342 yards per minute
