workout the answer

The expect time for Alejandro to arrive in Santiago is 1 pm.

Solution:

From the Question, Distance = 540 km

Start time from home = 6:15 am

Average speed = 80km/hr

We need to find the expect time to arrive in Santiago.

Using the time formulae:

where,

s = speed (meters/second)

d = distance traveled (meters)

t = time (seconds)

Substitute the given data in the formule

t =

= 6.75  

= 6 hours 45 minutes

Alejandro sets off from home at 6:15 am. So the expected time is calculated by adding 6:15 am to time found

Arrival Time = 6.15 am + 6hours 45 minutes = 1 pm.

Hence the expect time for Alejandro to arrive in Santiago is 1 pm.
