Question

Two cyclists start from the same point on a mountain. One travels 1200 m downward the mountain
in 20 minutes, and the other travels 350 m upward the mountain in the same time. How far are they
from each other after 20 minutes?​

Answer 1

Answer:

850 m

Step-by-step explanation:

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 .

Answer 2

Answer:

1550m.

Step-by-step explanation:

One cyclists travelled downward the mountain in 20 minutes = 1200m.

Another cyclists travelled upward the mountain in 20 minutes = 350m.

Therefore,

The total distance by both in 20 minutes = (1200+350)m. = 1550m.

So, The total distance by both in 20 minutes = 1 550m.
