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 first car be x

then speed of other car is (x+7)

distance covered by fist car after 2 hour = 2x

distance covered by 2nd car = 2(x+7) = 2x+14

now , 2x+2x+14+34 = 300

4x+14+34 = 300

4x+48 = 300

4x = 300 - 48

x = 252 / 4 = 63 km/hr

distance of 2nd car = 63 + 7 = 70km/hr
