the timing of a college is from 12 p . m to 4.20 p . m . six lectures are held in the given duration and a break of 5 minutes after each lecture is given to the students . find the duration of each lecture .
"explanation : total time a student spends in college = 4 hours 20 minutes = 260 minutes as there are 6 lectures , the number of breaks between lectures is 5 . total time of the break = 25 minutes hence , the duration of each lecture is = ( 260 â € “ 25 ) / 6 = 39 minutes answer d"
divide(multiply(4.20, const_60), 5)
