Abiker’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?

Answer : The speed of walker and biker is, 16.67 mile/hr and 25.005 mile/hr respectively.

Step-by-step explanation :

Let the walker’s speed be, 'x'

So, the biker’s speed will be, 1.5x

Given:

Time = 1.5 hours

Distance between walker and biker = 12.5 miles

As we know that,

The distance covered by walker =

The distance covered by biker =

Distance between walker and biker = 12.5 miles

So,

Thus, the walker’s speed = x = 16.67 mile/hr

The biker's speed = 1.5x = 1.5(16.67) mile/hr = 25.005 mile/hr

the answer to this is a. a^2 + b^2 = c^2
