Question

This distance between two stations is 300Km. two motorist start simultaneously from
their stations and move towards each other, the speed of them is 7 Km/hr. more than the
speed of the other (If the distance between them after 2 hrs. of their start is 34Km. Find
the speed of each motorist​

Answer 1

Answer:

distance between the two stations=300 km

let the speed of the first motorcycle be x km/hr

so according to the question the second motorcycle will have a speed of (X+7)km/hr.

so after 2 hrs,1 bike will have a speed of 2x and the 2 bike will have a speed of 2(x+7)

so now,

2x+2(x+7)+34=300

2x+2x+14+34=300

4x+48=300

4x=252

x=63

so first speed is 63 km/hr,and second speed is (63+7)=70 km /hr
