One moves at 60km/h, so in an hour, he’ll travel 60km
The other moves at 40km/h, so in an hour, he’ll travel 40km
This is towards each other, so, in an hour, we can say that they’ll get 60+40=100km closer.

This means that they get closer at 100km/h

Given that we have the distance of 150km, and the speed of closure at 100kmh, we can now use the equation

S=D/T

Rearrange to find T (times both sides by T)

S x T = D (now divide both sides by S)

T=D/S

Time = 150km divided by 100km/h

Time = 1.5 hours

Or one hour and 30 minutes

4. zoni says:

Can u plz give the solution of this question

5. noor nabi says:

simple hai agar dono k km dekhe jay to 1 hour me dono 100 km cover kr rahe hain matlb remainig 50 km bach gay to agar 1 hour me 100 km agar kr rhe hain to to 50 km half an hour me honge means total hours 1.5 lage

6. Rab Nawaz says:

Bro ye maths hai to yahan pe answers k sath solutiom b hona chahye jese smjh aa sake prove zaruri hai to lehaaza solution b diya hai data k sath. thanks

7. Shoaib abro says:

Why eds portion contains arithmetic?

1. thanks for pointing it out. it has been moved to maths section

8. Akramullah khan says:

Respected sir,
Sir physics ki koi mcqs book ka naam batayen

9. Iman says:

Solution?

10. Zulqarnain saahi says:

Suppose time = x hours
Both cars will have same time, but different distances depending upon speed.
So,

(60km/h).x + (40km/h).x = 150
(100 km/hour ).x =150
X= 1.5

11. Dear I need past ppsc papers of lect physics
If you have plz share me
Will be thankful to you

Simple is one is moving with 60km/hr means
150/60 = 2.5 hr
150/40 = 3.75 the difference between both is 3.75-2.5 = 1.25

13. Ahmed Ali Khuwaj says:

Speed = Distance/time
t=d/s
T1=150/60 =2.5
T2=150/40= 3.75
Meeting time=T2-T1
=3.75-2.5
=1.25
