1) Ephy left Naomi's house and drove toward her cabin on the lake. Valerie left one hour
later driving at 60 mph in an effort to catch
up to Ephy. After driving for two hours
Valerie finally caught up. Find Ephy's
average speed.

120mph to catch her

8121 because

130,000 divided by 16 is 8121

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
