Answer:
t'
f
t
Step-by-step explanation:
I assume you're asking for the scale? It would be 4:64, which simplifies to 1:16.
Let's assume that Kirby walks with a speed

for a time

, and that he runs with a speed

for a time

.
The total time available for Kirby to catch the train is:

and this must be equal to the sum of the two times t1 and t2:
The distance Kirby should cover is

and this should be equal to the sum of the distances covered by walking and by running:

So we have a system of 2 equations:


If we solve the system, we find:


So, Kirby needs to run at least for 8 minutes in order to catch the train.
Black 20% 1/5
navy 25% 1/4
Brown 35% 7/20
other 20% 1/5
