Question

By decreasing the speed of a Rickshaw by 4km/hr., it takes 3hours more to cover a journey of 360 km. Find the original speed of the Rickshaw .

Answer 1

Answer:

Step-by-step explanation:

Let the original speed is x km/hr

Time taken 360 /x

New speed x - 4

New time 360/x +3

Distance =360

(X-4)(360/x+3)=360

Solve and get your ans

Answer 2

Answer:

Step-by-step explanation:

Let's say that the initial speed of the rickshaw is x km/h and it takes t hours to cover a distance of 360 km.

So, we have our first equation :

speed * time = distance

Thus, x * t = 360

Now, if speed is decreased by 4 km/h , the time increases by 3 hours.

Therefore,

(x - 4) * (t + 3) = 360

Solving these two equations is now just pure algebra.

Replace t by 360/x and solve further.

We get the final answer as x = 24 km/h.
