Average speed = \frac{Total Distance}{Total Time}

Ishan's Speed uphill = 10mph

Time taken = 18 minutes = 18/60 = 3/10 hours

Now distance = rate × time

Distance traveled by Ishaan up hill = 10 × 3/10 = 3 miles

Now returning back home

Distance = 3 miles

Rate = 30 mph

So time taken = distance/ rate = 3/30= 1/10 hours = 1/10 ×60 = 6 minutes.

Now total distance traveled = 3 + 3 = 6 miles

Total time taken = 18 + 6 = 24 minutes = 24/60 = 2/5 hours

Average speed

= \frac{6}{0.4}

= 15 mph

Ishaan's average speed for the entire trip from home to the gift store and back is 15mph

The total number of cats and dogs at the shelteris 125. there are 5 more cats than dogs
juin [17]
If you're looking for the number of dogs (I'm assuming, you didn't specify), all you'd have to do is divide the number by two, then round down to find the number of dogs, then check your answer by adding that number and that number plus 5.

For example, yours would look like 125/6=62.5, and rounding down to 60.

Then check your answer by adding 60 and 65, the number of cats. 60+65=125.

There are 60 dogs inside the kennel.

The sum of the digits of a two-digit number is 13. If 27 is added to the number, the digits will be interchanged. Find the numbe
Lesechka [4]

Hello from MrBillDoesMath!

Answer:

58


Discussion:

Suppose the 2-digit number is "ab". That is, 10a + b.

Sum of digits = 13  =>  a + b = 13   (*)

Digits reversed if 27 added to number  => (10a + b) + 27 = 10b + a  (**)

(**) =

(10a + b) + 27 = 10b + a            => subtract 10b, then a, from both sides

9a -9b = -27                              => divide both sides by 9

a - b = -3

From (*),  a+ b = 13 so  

(a-b) + ( a+b) = -3 + 13  =>

2a = 10 =>

a = 5

As  a +b = 13, 5 + b = 13 => b = 8

Hence the number "ab" is 58


Thank you,

MrB

If 20 wall paintings can be done in 4 weeks how much time does it take to prepare 80 wall paintings using unit rate form?
In-s [12.5K]
Simplest way would be to find out how many painting more it would be 80 from 20. It is four times more drawings. Now since  you know it is 4x more then you can simply multiply 4 time 4 (4*4) because it would be the weeks it takes him by the times it would be. It would be 16 weeks in total.
