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:
[tex]time = \frac{distance}{speed}[/tex]
[tex]t = \frac{d}{s}[/tex]
where,
s = speed (meters/second)
d = distance traveled (meters)
t = time (seconds)
Substitute the given data in the formule
t = [tex]\frac{540}{80}[/tex]
= 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.
