It's an emergency! Anyone that can solve ex 13+14 of mixed exercise of chapter 7 C2 book please?! P.S. Merry Christmas!
you will need to post a photo of the page
you will get faster response if you post in the main maths section (forum 38)
Think with pics for q13 &remember to convert units, q14 is perhaps a little harder but isn't that bad..

I was doing it with a different way, like
16th: 6(1.2)
17th:6(1.2)^2 and so on... so that's why I am having trouble with 5

first part
75 minutes to cover 15 Km
so the pace is 5 minutes every km
so time increases by 20%
5 x 1.2 (minutes) for the the 16th km
(5 x 1.2)/60 (hours) for the the 16th km
and so on
