Answers:
Masuma - 30 seconds
Nashrah - 120 seconds
Harsha - 40 seconds
Explanation:
Masuma's finish time was half of Heathe's, so 60/2=30
It took Nashrah 4 times longer than Masuma to finish, so 30 x 4 = 120
Harsha was 3/4 of the way done when Masuma finished, so 30 = 3/4, meaning each 1/4 is equal to 10 seconds, making the finishing time 40 seconds.
Hope this helped!
