Answer:

6

Step-by-step explanation:

The absolute value of -2 is 2, but with the negative on the outside it would be -2.

I assume you're asking for the scale? It would be 4:64, which simplifies to 1:16.

Kirby is four miles from the train station, from which a train is due to leave in 56 minutes. Kirby is walking along at 3 mph, a
Luda [366]
Let's assume that Kirby walks with a speed 
v_1 = 3 mph
for a time t_1, and that he runs with a speed
v_2 = 12 mph
for a time t_2.

The total time available for Kirby to catch the train is:
t=56 min = 0.93 h
and this must be equal to the sum of the two times t1 and t2:
0.93 = t_1 + t_2 

The distance Kirby should cover is
S=4 m
and this should be equal to the sum of the distances covered by walking and by running:
4 = S_1 + S_2 = v_1 t_1 + v_2 t_2 = 3 t_1 + 12 t_2

So we have a system of 2 equations:
0.93 = t_1 + t_2
4 = 3 t_1 + 12 t_2

If we solve the system, we find:
t_1 = 0.80 h = 48 min
t_2 = 0.13 h = 8 min

So, Kirby needs to run at least for 8 minutes in order to catch the train.
