HELP PLZ A biker’s speed is 1.5 times faster than a walker’s speed. They start moving simultaneously in the same direction from the same point and, after 1.5 hours, the distance between them is 12.5 miles. What are their speeds?

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

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
