Completion Instructions

Functionality to be added

The app must have the following functionalities

• The speed should initially be 0mph

  Here mph means Miles per hour

• When Accelerate button is clicked,

  • If the speed is less than 200mph, the speed should be increased by 10mph
  • If the speed is equal to 200mph, the speed should not be increased

• When Apply Brake button is clicked

  • If the speed is greater than 0mph, then the speed should be decreased by 10mph
  • If the speed is equal to 0mph, the speed should not be decreased

Implementation Files

Use these files to complete the implementation:

• src/components/Speedometer/index.js
• src/components/Speedometer/index.css

Quick Tips

Things to Keep in Mind

• All components you implement should go in the src/components directory.
• Don't change the component folder names as those are the files being imported into the tests.
• Do not remove the pre-filled code
