Q:

Three  cars A, B and C  started  from  a  point at 5  pm, 6  pm  and 7  pm respectively and travelled at uniform speeds of 60 km/hr, 80 km/hr and x km/hr respectively in the same direction. If all the three met at another point at the same instant during their journey, then what is the value of x?

A) 120 B) 110
C) 105 D) 100
 
Answer & Explanation Answer: A) 120

Explanation:

Distance covered by A till 6pm = 60 km

Distance covered by A till 7 pm = 120 km

Time taken by B to catch A = 60/(80-60 ) = 3 hrs

So A and B will meet at 6pm + 3 hrs = 9pm

Since we know that all three met at the same time

The time taken by C to cover 120 km

difference will be  = 9pm –7pm = 2hrs

Therefore,(x –60 )*2 = 120x = 120 km/hr
