Question

- The distance between two towns is 300 km. Two cars start simultaneously from
these towns and move towards each other. The speed of one car is more than the
other by 7 km/hr. If the distance between the cars after 2 hours is 34 km, find the
speed of the cars.​

Answer 1

Answer:

let the speed of the car starting from town A be xkm/hr

and the speed of another car be x+7km/hr

after two hours,

distance coverd by car starting from town A is x*2 km

distance coverd by car starting from town B is (X+7)*2km

by the question,

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

=>2x+2x+14+34=300

=>4x+48=300

=>4x=300-48

=>4x=252

=>x=252/4

=>x=63

so the speed of the car from town A is 63km/hr the speed of the car from town B is (63+7)=70km/hr
