Jane runs 6 miles in 44 minutes. At the same rate, how many minutes would she take to run 9 miles?
polet [3.4K]

Answer:

66 minutes

Step-by-step explanation:

<u>Solve for speed</u>

speed = distance / time

speed = 6 / 44

<u>Substitute in speed to second equation and solve for time</u>

distance / speed = time

9 / (6/44) = time

66 = time taken

Liam went to the zoo with his parents and a ticket for the zoo cost's him $5.3. It costs an adult $10.70. How much would it cost
jarptica [38.1K]

Answer:

If 4 more kids came to the zoo with Liam and his two parents, and so did 4 more adults, the price they would pay would be:

5.3(5) + 10.7(6)

90.7

So, it would cost a total of $90.70 dollars for Liam, his two parents, four other friends, and four other parents, to come to the zoo.

Let me know if this helps!
