Mathematics
1 answer:
DochEvi [55]2 years ago

Answer:

Answer is 5,770 miles.

Step-by-step explanation:

okay we know ED = 240 miles

we know EC = ED + DC

EC = 240 + 3960

EC = 4200

we know in a right angled triangle, hypotenuse square is the sum of square of sides

EC^2 + CH^2 = EH^2

EH^2 = 4200^2 + 3960^2

EH^2 = 17,640,000 + 15,681,600

EH^2 = 33,321,600

EH = Root 33,321,600

EH = 5772.48

If we round to the nearest ten,

EH = 5770

skelet666 [1.2K]

Answer:

The answer to the question is

1.5 hours that is;

When the distance between them is more then 135 miles is after 1.5 hours and they will lose radio contact at 3:30 p.m.

Step-by-step explanation:

We note that

The speed of the military convoy headed north =50 mph

The speed of the convoy headed south  = 40 mph

Let t be the time taken for the two convoys to be 135 miles apart

The time taken for the two convoys to be 135 miles apart is given by

50×t miles+ 40×t miles= 135 miles

That is 90×t miles = 135 miles

                  t = 135/90 = 1.5 hrs
