Question

2 cycles start from same point on a mountain. 1 travel 1200m downward mountain in the 20 minutes and the other travel 350upward in the same time.. how far they from each other after 20 minutes ​

Answer 1

Given :

Distance traveled by 1st cyclist in 20 mins = 1200 m

Distance traveled by 2nd cyclist in 20 mins = 350 m

To Find :

How far are the 2 cyclists from each other after 20 mins = ?

Solution :

Since they have both started from the same point and are moving in opposite directions .

Lets assume the downward direction to be positive and upward direction to be negative :

So, distance traveled by the 1st cyclist = + 1200 m

And  distance traveled by the 2nd cyclist = - 350 m

So, the gap between them will be = 1200 + (- 350 )

                                                         = 1200 - 350 m

                                                         =850 m

So, after 20 mins they are 850 m far from each other .
