kaheart [24]
Yesterday's time:  t = 2 hr 20 min

Today's time:  0.73(2 hr 20 min) = 0.73 (2.333 hr) = 1.703 hr

This can be expressed in hours and minutes:
                                                              
                                                            60 min
1 hr + 0.703 hr  =  1 hr + 0.703 hr * --------------
                                                           1 hr

                            = 1 hr + 42.18 min

Rounded off to the nearest minute, we get 1 hr 42 min (answer)
