Ammar hikes 2 3/4 miles of nature trail in 1 hour and 15 minutes. how many miles of trail does ammar hike per hour?

2 3/4 miles in 1 hour and 15 minutes.
To makes things simpler , the fraction for miles will be converted into an improper fraction, so it will be 11/4.
For the time, there is 60 minutes in one hour, so 60 plus the 15 minutes is 75.

Now that the numbers are simpler, we can start to create cross products.

In 11/4 miles it takes 74 minutes. How many in 60 minutes ? So to find that, take 11/4 over x equals to 75 over 60. Cross multiply:
11/4 * 69 = 165
75 * x = 75x
The equation is now 75x = 165
Divide 75 in both sides to isolate variable x.
x = 2.2
2.2 in fraction form is 2 1/5 .
So finally it takes Amman to walk 2 1/5 miles per every hour.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
