Given; scooter charges consist of fixed charges and remain depending upon the distance travelled in kilometres. if a person travels 10 km, he pays rupee 28 and for travelling 16 km, he pays rupee 43
To Find; formulate simultaneous equations and hence find the fixed charges and the rate per km.
Solution; Let the fixed charges for the first km=x
The rate for subsequent km=y
According to question
x+9y=28
x+15y=43
Solving these two we get y=2.5 and x=5.5
Hence the fixed charge is 5.5 and the rate for subsequent km is 2.5
