For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:
Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
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.
