A certain industrial loom weaves 0.128 meters of cloth every second. Approximately how many seconds will it take for the loom to weave 15 meters of cloth?
Pick
A) 114
B) 115
C) 116
D) 117
E) 118

Rationale: let the required number of seconds be x more cloth , more time , ( direct proportion ) hence we can write as ( cloth ) 0.128 : 15 : : 1 : x = > 0.128 * x = 15 = > x = 15 / 0.128 = > x = 117 answer : d
Answer: D
