Question

(a)
speed of the cars.
12. 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
​

Answer 1

Step-by-step explanation:

let the speed of one car be x km per hour

then the speed of other car will be X + 7 km per hour

distance covered by first car equals to 2x km

distance covered by another car equal to to 2(x+ 7).

according to the question

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

2x+2x+14+34=300 km

4x+14+34=300km

4x+48 km=300km

4x=300-48 km

4x km= 300-48 km

4x=252 km

x= 252/4

x=63 km

speed of first car = X equal to 63 kilometre /hr

speed of second car equal to (x+7)=63+7=70 km/hr
