Answer:
Fixed charges = Rs 60 and the rate per km = Rs15 per km
Step-by-step explanation:
Let the fixed charges be x and the other charges be y per km.
Then, x+60y =960. ....... (1)
And, x+80y =1260. ......... (2)
On subtracting (1) from (2), we get
20y=300 =>y=15
Putting y =15 in (1),we get
x+(60*15)=960 =>x=960-900 =>x=60.
