Two cars, a Porsche Boxster convertible and a Toyota Scion xB, are traveling at constant speeds in the same direction. Suppose,

fenix001 [56]

Answer:

It will take 29.31 seconds for the Boxster to catch the Scion

Explanation:

Given the data in the question;

lets say Toyota Scion xB is car A and Porsche Boxster convertible is B and Toyota Scion xB is car A

the distance travelled by car A is

x = $V_{A}$ × t

where $V_{A}$ is the speed of the car and t is time

the distance travelled by car B before reaching car A will be;

x + x₀ = $V_{B}$ × t

Now lets replace x by $V_{A}$ × t

( $V_{A}$ × t) + x₀ = $V_{B}$ × t

x₀ = ( $V_{B}$ × t) - ( $V_{A}$ × t)

x₀ = t ( $V_{B}$ - $V_{A}$ )

t = x₀ / ( $V_{B}$ - $V_{A}$ )

so we substitute

t = 170 m / (24.4 - 18.6)

t = 170 / 5.8

t = 29.31 s

Therefore; it will take 29.31 s for the Boxster to catch the Scion
