1b(i)
it will be 13 hours and 16 mins

5c
(i)4/25x3/24 =1/50 will be the answer..
(ii)2/25x5/25=1/30

i would have done 8 if i had graph.

thnk u soo much..

1)similar triangles same angles of of a particular side of both triangle
suppose triangleABC= triangleXYZ therefore <A=<X ,, <B=<Y ,, <C=<Z

2) and they have same ratio of concerned sides
suppose triangleABC= triangleXYZ

then AB/XY= BC/YZ = AC/XZ

hoped understand!!

Thank you

q(1)(b)(i) just difference from may 7 to may 6 i.e 00 36+24 ( add 24 bcuz of being next day)

24 36 - 11 20 => 13h 16m

5(c) for 1 time it would be 4/25 and for second 3/24 multiply both

(ii) little bit confused according to my knowledge we should do 2/25 x 5/24 and ans should be 1/60 but correct ans = 1/30!!!

thnk u.. i thnk i found out the 5(c) (ii). we should do (2/25x 5/24)+(5/25x 2/24)

AGAIN WRONG SPIDEY NOW ITS 1/60 AND THE CORRECT ANSWER IS 1/30!!!!

THNX for the correct method !!!

thnk u soo much..

well there will be two possibilities
khizer shahab
it will be 1/30

cuz it will be 1/60+1/60= 2/60=1/30

well the similiar triangles are not completely equal but have 2 things same
like they might have an angle same and a side same which will make it a similar triangle...

similar triangles must have all three angles same!!!!
