a) how long does it take for them to meet at the starting point again?
b) how many laps will each boy have run by then ?​

Answer 1

Answer:

A)336 SECONDS

B)LAPS BY VENU=7 LAPS

  LAPS BY TANUJ=6 LAPS

Step-by-step explanation:

TIME TAKEN BY VENU TO COMPLETE ONE CIRCULAR TRACK=48 SECOND

TIME TAKEN BY TANUJ TO COMPLETE ONE CIRCULAR TRACK=56 SECOND

A) IN ORDER TO FIND ANOTHER MEETING POINT, WE HAVE TO FIND THE LCM OF 48 AND 56

SO,

LCM OF 48,56= 336 SECONDS

SO, THEY WILL MEET AFTER 336 SECONDS

B) LAPS TAKEN BY VENU=336/48

                                           =7 LAPS

   LAPS TAKEN BY TANUJ=336/56

                                            =6 LAPS
