Answer 1

Answer:

Step-by-step explanation:

Answer 2

The distance traveled by bike is 125/6 km

Step-by-step explanation:

Let the distance traveled by bike be x

Speed of bike = 25 km/hr

$Time = \frac{Distance}{Speed}=\frac{x}{25}$

Total distance traveled = 120 km

So, Distance traveled by foot= 120-x

Speed on foot= 7 km/hr

$Time = \frac{Distance}{Speed}=\frac{120-x}{7}$

Total time = 15 hours

So, $15 = \frac{x}{25}+\frac{120-x}{7}\\x=\frac{125}{6}$

Hence The distance traveled by bike is 125/6 km
