Or you could also say that Kevin takes$$T$$minutes to travel to work whilst Jane takes$$\frac{9}{10}T$$minutes.

anonymous · Answer

given:  $$\tau$$ = number of minutes of travel, by both kevin and jane.

$$\tau$$= number of minutes consumed by kevin


jane :  travels 10% faster than kevin.
       =T - T(10%); jane consumed number of minutes
