Answer #1

Let the total distance be x km

Speed = distance/time

Jim drove furst half of the trip at 110 km/hr

x/2 km at 110 km/hr

Time = distance/speed = (x/2)/110

Time for first half = x/220 hours

Jon drove second half at 80 km/hr

Remaining x/2 km at 80 km/hr

Time = distance/speed = (x/2)/80

Time for second half = x/160 hours

Given Total time taken for complete trip = 3 hours 30 minutes = 3.5 hours

Time for first half + Time for remaining = 3.5 hrs

x/220 + x/160 = 3.5

x(160+220)/35200 = 3.5

380x = 3.5 (3520)

x = 324.2 km

Therefore, it is 324.2 km to Tofino.

If a substance is radioactive, this means that the nucleus is unstable and will therefore decay by any number of processes (alpha decay, beta decay, etc.). The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions: lnAtA0=−ktlnAtA0=−kt and t1/2=0.693kt1/2=0.693k where A0A0A_0 is the initial amount or activity, AtAtA_t is the amount or activity at...
