Question

6. A and B start from the same point and at the same time with speeds 15 kmin
and 12 km/h respectively. Find the distance between A and B after 6 hours if both move
in :
(i) same direction
(ii) the opposite directions.
​

Answer 1

Answer:

(i) 5328km

(ii) 5472km

Step-by-step explanation:

(i)

First convert the 15 km/min into km/hr

60min = 1hr so:

900km/hr

then find out their respective distances in 6 hours

the first one will be 5400 km away and the second one will be 72 km away

5400 - 72 = 5328km

(ii)

use the same method as before but instead of subtracting, add.

5400 + 72 = 5472km
