Answer»

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
