Walking Rates

Amel helped his younger brother, Bonne, to determine his walking rate. Amel's rate was 2.5 meters per second, and Bonne's was 1 meter per second. Bonne challenges Amel to a walking race, and Amel gives Bonne a head start of 45 meters. Determine the distance and time required for Amel to overtake Bonne.

How long should Amel make the race if he wants his brother to win?
