Nidhi ran the 100 metres dash (means run/ stretch ) in 12.16 seconds. Her twin sister vidhi ran it in 14.6 seconds. By what per cent nidh's time differ from her sister vidhi

Answer 1

Answer:

Time taken by Naina to run 100 m = 12.16 seconds

Time taken by Diana to run 100 m = 14.6 seconds

Difference between their time durations,

Time taken by Diana - Time taken by Naina

=> 14.6 - 12.16

=> 1.44 seconds

Percentage of difference between their time durations,

( 1.44 / 12.16 ) * 100

=> 14400 / 1216

=> 7200 / 608

=> 3600 / 304

=> 1800 / 152

=> 900 / 76

=> 450 / 38

=> 225 / 19

=> 11×16/19%
