Question

At the rate of f feet per s seconds, how many feet
does a pedestrian travel in m minutes?
​

Answer 1

Answer:

m minutes is 60m seconds, and since distance = speed*time, the distance traveled will be (f/s)(60m) = 60mf/s.

There are many other ways to get the answer here. Instead, one could notice we need to convert minutes to seconds, so a '60' will need to appear in the right answer. The more time a person travels, the further they will go, so m will need to be in the numerator of the right answer (not in the denominator). And the bigger f is, the faster the person is traveling, and the further the person will travel, so f must also be in the numerator. That only leaves one possible answer choice, 60mf/s.

Step-by-step explanation:

Here the calculation simply asks us for distance traveled in feet. So the seconds need to cancel out completely.

We know that 1 minute has 60 seconds, therefore m minutes has 60m seconds.

We are given that in s seconds he travels f feet = 

Therefore in m minutes = 60m * = 60fm/s
