Wish to create another app that can check the distance travelled by multiple delivery boys each day

  1. The app has to give the detail about no. of delivery boys and how much distance they are travelling.

  2. The app has to calculate Total petrol expense as well, ie 2.5 inr per km. eg, If 10 two wheelers are run by delivery boys, then I wish to check about how much petrol expense has been spent collectively.
