Given : travelling salesman gets conveyance allowance rs. 5 per km from his employer. the salesman is travelling from bangalore to chennai. while going to chennai he travales at an avreage speed of 64kmph and on his return his avrage speed is 80kmph. he takes 9 hours for the double journey
To Find : the distance betweeb bangalore and chennai?
how many can be claim as travelling allowance from his employer?
Solution:
bangalore to chennai - avreage speed of 64kmph
chennai to bangalore - avreage speed of 80kmph
Let say Distance between bangalore chennai = D km
Time = Distance/ Speed
bangalore to chennai Time = D/64 hr
chennai to bangalore Time = D/80 hr
=> D/64 + D/80 = 9
=> multiply both sides by 320
=> 5D + 4D = 320 * 9
=> 9D = 320 * 9
=> D = 320 km
distance between bangalore and chennai = 320 km
Total Distance Covered = 320 + 320 = 640 km
conveyance allowance rs. 5 per km
travelling allowance claimed from his employer = 640 * 5 = 3200 Rs
