A toy train crosses 210 and 122 m long tunnels in 25 and 17 seconds respectively. Find the length of train and speed of train.
Read Solution (Total 2)
-
- Let the length of train be x m.
so,
distance = speed * time
x + 210 = s * 25-------(1)
x + 122 = s * 17-------(2)
by solving equation 1 and 2
we get s = 11 m/s
and x = 65 m - 6 years agoHelpfull: Yes(3) No(0)
- let speed of the train be u m/s and length of train be x m.
so,
x+210=u*25----(1)
x+122=u*17-----(2)
divide equation 1 by equation 2
x=65 m and u=11 m/s. - 6 years agoHelpfull: Yes(1) No(0)
