2).125 min to cover 10km,
125:10::375:xa
125×x=10×375
125×x=3750
x=3750÷125
x=30
therfore, Rohith covers 30km in 375 min.
3). Its is 19.266
By this method I do this
YU know that ,
Direct proportion= x1/y1=x2/y2
= 136/34 =x2/5.1
=Now we can do here cross multiplication
=136X5.1/34=x2
x2=19.266
and the shelf length is 34 m
4).Given Speed of the train = 36km/hr
= 36 * 5/18
= 10m/sec.
Given that train crosses the pole in 15 seconds.
Then the length of the train = Speed * Time
= 10 * 15
= 150m.
