If I run 2 1/2 miles in 19 1/5 minutes what is my average time per mile

7:41

Step-by-step explanation:

19 1/5 as a decimal is 19.2, and the mileage would be 2.5. to find the time per mile, you divide the finish time by the number of miles you ran:

  19.2 / 2.5 = 7.68

now you're prolly wondering, "why isn't the answer 7.68?" that's a good question, and the reason that 7.68 isn't the answer is bc time is all in factions of 60, not 100 like most things, so there are 60 seconds in a minute, instead of 100 seconds in a minute.

so, you have to find out how many seconds are in 0.68 of a minute. to do this, you multiply 60 by 0.68:

  60 x 0.68 = 40.8

so 0.68 of a minute is 40.8 seconds, so your average pace was 7:40.8. i would just round up to 7:41, but your teacher may want exact numbers.

hopefully that helps and isn't too confusing! if you need any other help, let me know! :)

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
