Answer 2

Answer: Speed of walker and biker will be 16.67 miles per hour and 25 miles per hour respectively.

Step-by-Step explanation:

Leave the speed of a walker alone x

Let the speed of a biker be 1.5x

They are moving a similar way,

thus, their Relative speed will be

1.5x - x =0.5x

Time taken = 1.5 hours

Separation between them = 12.5 miles

As we probably am aware the equation for "Distance":

*Picture attached*

Consequently, the Speed of the walker be 16.67 miles every hour

Speed of biker be

1.5 times 16.67=25 miles per houe
