A Car Travels A Distance Of 170 Km In 2 Hours Partly At A Speed Of 10

1.	A Car Travels A Distance Of 170 Km In 2 Hours Partly At A Speed Of 100 Km/h And Partly At 50 Km/h. The Distance Travelled At A Speed Of 50 Km/h Is?
Answer» Suppose he covers X KM at 100 kmph So he covers 170-x at 50 kmph So {X/100}+{170-X}/50=2 SOLVING this equation, we get x = 140. So he covers 30km at 50 kmph. Suppose he covers x km at 100 kmph So he covers 170-x at 50 kmph So {X/100}+{170-X}/50=2 Solving this equation, we get x = 140. So he covers 30km at 50 kmph.

Answer»

Suppose he covers X KM at 100 kmph

So he covers 170-x at 50 kmph

So {X/100}+{170-X}/50=2

SOLVING this equation, we get x = 140.

So he covers 30km at 50 kmph.

Suppose he covers x km at 100 kmph

So he covers 170-x at 50 kmph

So {X/100}+{170-X}/50=2

Solving this equation, we get x = 140.

So he covers 30km at 50 kmph.
