I think the answer is 7. 5 miles

Answer:

7.5mph (1 d.p)

Step-by-step explanation:

First, I worked out what a third of an hour was to match the unit mph.

60 minutes / 3 = 20 mins

A third of an hour is 20minutes so two thirds of an hour is 40 minutes.

But as we know, one third as a decimal is 0.33(reccuring) so therefore two thirds as a decimal is 0.66, which we need to use.

Now, we need to remember the equation. Speed = distance / time

Place the facts we already know in place.

speed = 5miles / 0.66 (using a calculator.)

speed = 7.5mph (1 d.p)

Hope this helps and you have a good day!

Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45
