The buses leave to the hall every 16 minutes and the central buses leave every 10 minutes. both leave at 4 p. m.find the next time both buses will leave

Both leave at 4 pm . The next time they will leave at 5:20 pm

Step-by-step explanation:

Taking LCM of 16 and 10

16= 2*2*2*2

10= 2*5

LCM= 2*2*2*2*5=  80

1 hour = 60 mins

80/60= 1 hour 20 minutes

Both leave at 4 pm . The next time they will leave at 5:20 pm

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
