Answer:

8:30 pm

Step-by-step explanation:

step 1

Decompose the numbers in prime factors

$30=(2)(3)(5)\\35=(5)(7)$

step 2

Find the LCM

The LCM of 30 min and 35 minutes will be given as

$LCM=(2)(3)(5)(7)=210\ min$

step 3

Adds 210 minutes to the starting time

First, converting 210 minutes to hours

Remember that

$1\ h=60\ min$

will need dividing 210 by 60

$210/60=3.5\ h$

therefore

5:00 pm+3.5 h=8:30 pm
