Answer 1

To find the required proportion, you first write down the proportion between the distance you walk and time, just as follow:

proportion = 2/35

In this case numerator is distance and denominator is time in minutes.

Now, if you want to know hof war you would walk in 1 hour (60 mins) with the same rate, you can write:

for 1 hour:

x/60 =

x is the uknown distance, which have to stay in the numerator, and denominator is 60 because 1 hour = 60 mins.

But the two previous expression must be equal because you walk at the same rate both times. Hence, the searched equation is:

2/35 = x/60
