Question

If I traveled 32 miles in 45 minutes, how long will I travel in one hour at the same rate?

Answer 1

32 X 60 : 45 = 42,6

42,6 miles in 60 minute

1 hour= 60 minute

cross product:

miles: 32 | ?

------------|-----------

time: 45 | 60

Answer 2

42 2/3 miles

Explanation:

We want write ratios to solve

We want the same units so change 1 hour to 60 minutes

32 miles x miles

----------------- = -----------------

45 minutes 60 minutes

Using cross products

32 * 60 = 45x

Divide each side by 45

1920/45 = 45x/45

42.6(repeating) = x

42 2/3 miles
