Question

Sanjay and jacob start run in opposite direction from same point at speed of 7 meter per sec and 5 meter pe sec after 42 min how far would they each other

Answer 1

Answer:

504 m

Explanation:

Sanjay and jacob start run in opposite direction from same point at speed of 7 meter per sec and 5 meter pe sec after 42 min how far would they each other

Sanjay Speed = 7 m/s

Jacob Speed = 5 m/s

As Sanjay and jacob start run in opposite direction so their relative speed will be addition of both speed

= 7 + 5 = 12 m/s

Time = 42 min

Distance = Speed * Time = 12 * 42  = 504 m

If they run in same direction then relative speed = 7-5 = 2m/s

Distance = 42 * 2 = 84 m
