Answer:
Explanation:
distance between the stations = 300km
let the speed of the first motorcyclist be (x)km/h
so according to the question the second motorcyclist speed will be (x + 7) km/h
after 2 hours the speed of the mortor cyclists are 1st biker = 2 x (x ) = 2xkm/h
2nd biker = 2 (x + 7) = (2x + 14) kmph
so according the question
2x + 2 (x + 7) + 34 = 300
2x + 2x + 14 + 34 = 300
4x + 48 = 300
4x = 300 - 48
x = 252/4
x = 63 kmph
x + 7 = 70 kmph
