Jimmy is trying to escape Jane

For finding total distance , we will find distances and then add them

He runs 12 km/hr for 5 minutes

First distance:

speed =12 kh/hr

time=5 minutes

we can change into hour

$t=\frac{5}{60}hr$

$d_1=s*t$

now, we can plug values

$d_1=12*\frac{5}{60}$

$d_1=1$

second distance:

speed =17 kh/hr

time=8 minutes

we can change into hour

$t=\frac{8}{60}hr$

$d_2=s*t$

now, we can plug values

$d_2=17*\frac{8}{60}$

$d_2=2.26667$

third distance:

speed =6 kh/hr

time=2 minutes

we can change into hour

$t=\frac{2}{60}hr$

$d_2=s*t$

now, we can plug values

$d_3=6*\frac{2}{60}$

$d_3=0.2$

now, we can find total distance

$d=d_1+d_2+d_3$

$d=1+2.26667+0.2$

$d=3.46667$

so,

total distance is 3.46667 km...........Answer

The function is given $f(x)=2^x+3$ .

Now let's solve for $f(-2)$ .

$f(-2)=2^{-2}+3$

Rule of negative exponent: $x^{-1}=\frac{1}{x^1}$ .

$f(-2)=\frac{1}{2^2}+3$

$f(-2)=\frac{1}{4}+\frac{3}{1}$

Rule for sum of fractions: $\frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}$ .

$f(-2)=\frac{13}{4}$

And the result is:

$f(-2)=\boxed{\frac{13}{4}=3.25}$
