Question

Mrs smalls is sewing a sweater for her grandson. It took her 1/5 hour to sew 2/7 inch. How fast is Mrs smalls sewing speed in inches per hour

Answer 1

Answer: 1.4285 inches/hour

Step-by-step explanation: 1/5 of an hour is equal to 20%, or 0.2 hours. 2/7 inch is equal to 0.2857 inches, approximately. If she sews 0,2857 inches in 0,2 hours, we can cross multiply the values we want to discover:

x inches  -  1 hour

0.2857 inches - 0.2 hours

$x.0.2=0.2857.1\\\\x=0.2857/0.2\\x=1.4285$

Then, 1.4285 inches are sewed in one hour.
