Answer to Problem 20P

The walking speed of Bill is 4mi/hr and the speed of Bike is 12mi/hr .

Explanation of Solution

Given:

The distance from Bill house to Fred’s house is 3mi .

The distance between the Fred house to the school is 1mi .

The time taken to reach from Fred house to school is 30min .

The time required by Bill to ride to school only on bike is 20min .

Calculation:

Consider the speed of the bike is b and the speed of the walk is w .

The total distance travelled is,

  3+1=4miles

The time taken to by Bill to reach from home to school on bike is,

  20min=20min60min=13hours

The time taken by Bill to reach school on bike is,

  4mi=(13hours)bb=12mi/hr

The time taken by Bill to reach Fred house on bike is,

  3mi12mi/hr=14hour=15min

Then, the time taken by Bill to reach school from Fred house is,

  30min15min=15min

Thus, the walking distance from Fred house to school is 1mi that takes 15min . Then the walking speed of the Bill is,

  w=1mi14hour=4mi/hr
