PLS I NEED HELP IT'S FOR TOMORROW!! :(

Step-by-step explanation:

10)We have to calculate the average speed if we know the distance and time that Johnatan can jog. The distance

distance=3 2/5 miles = 3.4 miles.

Time=7/8 hour = 0.875 h

Then we will use the formula for the average speed ( velocity )

velocity=distance/time. v = 3.4 m / 0.875 h = 3.866 mph

so therefore The average speed is 3.866 mph.

11) divide 120 / 7/4 (remember 120 = 120/1)

Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).

Then 120x4= 480

And 1x7 = 7

Then you get 480/7, which is the same as 68 4/7 mph

12)8 1/3=25/3

   25/3 pages of a book in 10 minutes

   Multiply both numbers by the reciprocal of 10, which is 1/10

  25/3 x 1/10=25/30=5/6

  10 x 1/10=1

So, Charlotte reads 5/6 pages of a book in 1 minute.

13)45 1/2% = 45.5% = 45.5/100 = 91/200

30 1/4% = 30.25% = 30.25/100 = 121/400

75 1/3% = 75.3333...% = 75.333.../100 = 11/15
