A baby crawled 50­ 1 /4 yards in 20­ 1/ 2 minutes.

At this rate, how far could

she crawl in one minute?

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
