Answer:
690 miles
Step-by-step explanation:
Step one:
given data
For the first plane
the velocity is 300km/h
from noon (12:00) to 2pm is= 2 hours
the distance covered is expressed using the formula
velocity= distance/time
distance= velocity*time
distance= 300*2
distance= 600 miles
For the second plane
the velocity is 45km/h
from noon (12:00) to 2pm is= 2 hours
the distance covered is expressed using the formula
velocity= distance/time
distance= velocity*time
distance= 45*2
distance= 90 miles
Step two:
the total distance apart is the sum of the individual distances covered by the planes
= 600+90
=690 miles
