Question

The distance between two station A and B age 310 kilometre to motorcycle start simulation early from A and B in the opposite direction and distance between them after 4 hours is 30 kilometre if the speed of one motor scholastic is less than that of the Other by 10 kilometre per hour and the speed of each motorcyclist​

Answer 1

hi

total distance= 310

let the speed of 1 train be x

then other would be x+10

total speed = 2x+10

total distance after 4 hours = 280

s×t= d

4(2x+10)= 280

8x+40=280

x= 60

speed of 1 train = 60kmph

speed of 2 train = 60+10=70kmph
