Question

a man covers a distance with the speed of 45 km/h.when he increase the speed upto 60km/h then it takes him 5 hrs less than earlier. find the total distance of the journey.​

Answer 1

Answer:

easy bro

Step-by-step explanation:

a man covered distance of speed up to 45kmph

he increase speed up to 60 kmph then it takes 5hrs

so to find total distance 60-5 for actual distance 45 +10 for earlier one

total distance on journey is 55

Answer 2

Given,

Speed of the man = 45 km/h

Then speed is increased to 60 km/h and it takes 5 hrs less to cover the distance.

To Find,

The total distance of the journey.

Solution,

Let the total distance of the journey be x km.

Now,

In first case

Time = distance/speed = x/45

In second case

Time = (x/60)+5

Since, the time taken in both the cases will be same

So,

x/45 = x/60-5

x = x/60*45-5*45

x = 3x/4+225

x/4 = 225

x = 900 km.

Hence, the total distance of the journey is 900 km.
