Question

Archana starts journey from Delhi at 8 am for jaipur. Her car is running at a speed of x km/hr . If at 1 pm , she observes that she is 20 km away from jaipur, find the distance between Delhi and jaipur.

[Hint : Distance = speed × time]

Answer 1

Answer:

5x + 20 km

Step-by-step explanation:

Given, Speed = x km/hr

Time = 8 Am to 1 PM{Duration - 5 hours}

We know that Distance = Speed * Time

                                       = (x) * 5

                                       = 5x.

It is said that She observes that she is 20 km away.

So, the distance between Delhi and Jaipur = 5x + 20 km.

Hope it helps!

Answer 2

Answer:

5x+20 km

Step-by-step explanation:

speed of car = x km/h

time = 5 hrs (from 8am to 1pm)

we know that speed = distance/ time

distance = speed*time

distance = (5x+20)km

hence distance between jaipur to delhi is 5x+20 km.
