Time Distance and Speed
a is twice as fast as b and b thrice as fast as c is the jouney covered by c in 42 min. will be covered by a in
Read Solution (Total 2)
-
- 7 min
If the speed of a,b & c are A,B & C respectively
Given A=B/2 & B=C/3 ,
So A=C/6,If time taken by c is 42 min.,then by a= 42/6= 7 min. - 10 years agoHelpfull: Yes(8) No(0)
- speed of c = x
then speed of b = 3x
speed of a =2(3x)
So b will complete the distance in = 42/3 = 14
and a will do that in half the time taken by B so it will be 7 Min. - 8 years agoHelpfull: Yes(0) No(0)
