67. (a) In regions where the speed is constant, it is equal to distance divided by time. Thus, we conclude that the time diference is t = µ L d V + d V V L V where the Frst term is the travel time through bone and rock and the last term is the expected travel time purely through rock. Solving ±or d and simpli±ying, we obtain d =∆ t V ( V V )

Unformatted text preview: V t V 2 V . (b) I we estimate d 10 cm (as the lower limit o a range that goes up to a diameter o 20 cm), then the above expression (with the numerical values given in the problem) leads to t = 0 . 8 s (as the lower limit o a range that goes up to a time diference o 1 . 6 s)....
