How did u know it was 60 ?

it an equilateral triangle cause its formed from the diameters of the circles

MEANS IN 2 DIAGRAMS ONLY OUTSIDE REGION WILL BE THERE

read my post again i explained

How did u know it was 60 ?

you know tangent from a point are equal
when all the tangents are able to meet means all are
equal since 3 sides are equal all 3 angles are equal
18/3=60

 

[MERIHAN]

yes i think that is the ans. bec. he wants the intersection then ^ so the middle gap will not be shaded

i saw the video on youtube and the man says on the same question that you should shade only the outside..thats what is confusing me

just add up the distances which is 3+3 and divide them by time in hours so 1 hour and 30 minute is equal to 1.5 so 6/1.5 it will give u an answer of 4

oh sorry wrong questions well i had a problem with that but i realized i was calculating area down to the truck axis not time axis just calculate the area of the square under the truck from 15 seconds till 55 which is equal to 480 then split the part above the truck axis to 2 right angled triangles find there combined area which is also equal to 480 this will give u an answer of 960
