Two buses depart two cities moving in the same direction. The speed of the first bus is 54 mph which is 60% of the speed of the

Stells [14]

Answer: Distance between the buses 24 minutes after the departure is given by $36-21.6=14.4\ miles$

Step-by-step explanation:

Since we have given that

Speed of first bus = 54 mph

Speed of second bus is given by

$54=60\%\times \text{Speed of second bus}\\\\\dfrac{54}{0.6}=\text{Speed of second bus}\\\\90\ mph=\text{Speed of second bus}$

Distance covered in 24 minutes by the first train is given by

$54\times \dfrac{24}{60}\\\\=21.6\ miles$

Distance covered in 24 minutes by the second train is given by

$90\times \dfrac{24}{60}\\\\=36\ miles$

Hence, Distance between the buses 24 minutes after the departure is given by $36-21.6=14.4\ miles$
