dumbcow help me............
speed = 20kmph andlength =100/3 meter but dont kno hw to solve
not sure on this one does it take 15 sec to pass both

no 12 sec and 15 sec respectively
ok got it d = r*t r is speed of train d is distance of train t is time it take to pass each cyclist also need to convert from km/hr to m/s 1km/hr = 10/36 m/s cyclist 1: d = (r-10)(10/36)*(12) cyclist 2: d = (r-12)(10/36)*(15) to find r set 2 equations equal (r-10)(10/36)*12 = (r-12)(10/36)*(15) (10/36) cancels 12r -120 = 15r - 180 -3r = -60 r = 20 substitute this back in to find d d = (20-10)(10/36)*12 d = 1200/36 d = 100/3
Let the speed of the train be v Thus, the relative speed of c1 = v-c1=v-10 the relative speed of c2 = v-c2=v-12 Now, speed = length of the train/time to cross the cycle v-10=L/12 and v-12=L/15 Therefore L/12+10 = L/15+12 L+120/12=L+180/15 15L+120*15 = 12L + 12*180 3L = 12*180 - 120*15 L = 4*180 - 40*15 =40(18-15) =40(3) 120.
you forgot to convert to m/s for speed because time is in sec
I didn't
Ya right, sorry!
I don't know why they haven't given the option to delete answers!
amit did that help you understand
yes
