A distance cover in 30hour .if rate 1/15 the coverd distance decrige 10 km.what is rate.

Answer :

Basilisk
time = 30 hour
Speed = distance / time
   (1/15)y = 10
            y=150 km
y is the distance

speed or rate = distance / time
                    = 150 /30
                    = 5km/hr

The rate required to travel 150km in 30 hr is 5km/hr.

Answer

Let the time he walks be x hours

From the given condition

3(x)+9(3−x)=15

⟹6x=12

⟹x=2

⟹x=2So the time he runs is 3−2=1 hour

Distance covered by running is 1×9=9 km
