Question

6. - Laura es piloto comercial. Cada semana realiza cinco viajes de ida y vuelta entre Santiago de Cali y Cartagena. La distancia entre ambas ciudades es de 782 Km. Laura estima que en seis semanas recorre más de 40.000 Km, que es como dar la vuelta al mundo. ¿Tiene razón Laura?

Answer 1

Distance between city , D = 782 km.

Number of trips in a week , n = 5.

Total distance covered in a week , d = D × n = 782 × 5 = 3910 km.

Now, distance covered in six weeks is :

`D'=d* 6\\\\D'=3910* 6\ km\\\\D'=23460\ km`

Therefore, her assumption of travelling 40,000 km in six week is wrong.

Hence, this is the required solution.
