Answer:

f(12) = - 20

Step-by-step explanation:

Question 2:

Helga [31]

Answer:

15mins

Step-by-step explanation:

Given that he worked out a total of 360mins, and jogged 45mins/day:

$Jog \ Time=Total \ Time- Bike \ Time\\=360-(45\times6)\\=90min$

Therefore, Allen jogged a total of 90mins in the past one week. To calculate the time jogged each day, we divide the total jog time by number of days jogged:

$t_d=Total \Time/(No \of \ Days)\\=90/6\\=15mins$

Allen jogged 15mins per day.
