Distance = 400 km \\ time = 2 hrs \\ speed =  \frac{Distance}{time}  \\  =  \frac{400km}{2hrs}  \\  = 200km/hr \\  \\ Distance =  ? \\ time = 5hrs \\ speed = 200km/hr  \\ speed =  \frac{Distance}{time}  \\ 200km/hr =  \frac{Distance}{5hrs}  \\ 200 \frac{km}{hr}  \times 5hrs = Distance \\ 1000km = Distance

Step-by-step explanation:

Let the distance travelled at 100 km/hr be x km.

Then, distance travelled at 50 km/hr is (170 - x) km.

Given,

100

x

+

50

(170−x)

=2

100

x+2(170−x)

=2⇒x+240−2x=200

⇒x=140km.

∴ Distance travelled at 50 km/hr =(170−140)km=30km
