Work Step by Step
Charlene started to ride a bike to her friend's home. After $3$ miles of bike riding, her bike got a flat tire. She walked the $2$ remaining miles. On her way back home, she walked the whole way: $2+3=5$ miles. She walked a total of: $5+2=7$ miles. This means that she walked: $7-3=4$ more miles than she rode her bike.
