Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting
kodGreya [7K]

Josiah and Chana travel at constant and different speeds.

  • The point F indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana

<h3>How can the what the the point <em>F </em>represent be known?</h3>

Josiah's head start = 10 meters from the start

Josiah's speed = 2 m/s

Chana's speed = 3 m/s

Expressing the distance traveled as an equation, we have;

D = d + s × t

Where;

D = The distance covered

d = The distance from the starting line the runner starts

s = The speed of the runner

t = The time spent running

For Josiah, we have;

D = 10 + 2•t (line <em>a</em>)

For Chana, we have;

D = 0 + 3•t = 3•t (line <em>b</em>)

The above equations are straight line equations.

The point <em>F </em>is on line <em>a</em>, which shows Josiah distance after 25 seconds which is 60 meters. The corresponding point on line <em>b</em>, Chana's distance after 25 minutes is 75 meters.

Therefore;

  • The point <em>F </em>indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana
