Answer:
x = 2.45 yards
Explanation:
Given the following data;
Distance = 50¼ yards = 201/4 = 50.25 yards
Time = 20½ minutes = 20.5
To find the distance covered in a minute;
50.25 yards = 20.5 minutes
x yards = 1 minute
Cross-multiplying, we have;
x * 20.5 = 50.25 * 1
20.5x = 50.25
x = 50.25/20.5
x = 2.45 yards
Method II.
201/4 yards = 41/2 minutes
x yards = 1 minute
Cross-multiplying, we have;
x * 41/2 = 201/4
41x/2 = 201/4
41x * 4 = 201 * 2
164x = 402
x = 402/164 = 201/82 = 2 37/82 yards
