Question

a horse trots uniformly along a circular track of radius 21 ft . The angle subtended at the centre of the track by the arc described by the horse in 2 sec is 60 degree . what distance will the horse pass over in a minute
​

Answer 1

Answer:

1 circle

Step-by-step explanation:

1 circle  = 360 deg

so 60 deg = 1/6 of circle's circumference

total circumference = 2 x22/7 x 21

= 132

so distance covered = 1/6 x 132

= 22 ft
