Two boats leave the jetty at the same time. one of them returns to the jetty every 25 minutes and the second one returns every 30 minutes. When will the boats next be at the jetty at the same time

150 min or 2 hours 30 min

Step-by-step explanation:

find the common multiple

30 60 90 120 150 180 210 240 270 300

25 50 75 100 125 150

both have 150 so the first time they meet is 150 or 2 hours 30 min

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
