Show work please (6th grade math)

Answer 1

The answer is 48 miles.

To find how long the bus travels in 60 minutes, we need to find a ratio of how long the bus travels every 15 minutes.

We do this by dividing 45 minutes by 3. We now have 15 minutes.
You then divide the miles by 3 as well. 36 divided by 3 is 12.

A bus travels 12 miles every 15 minutes.

Now, this still isn't the answer. We need to find how many miles the bus travels in 60 minutes. 

To find this, we need to find how many 15 minute intervals are in 60 minutes. To do this, we divide 60 by 15 to get 4. We use this 4 to multiply it by 12 to find the total number of miles in 60 minutes.

12 times 4 is 48 miles.

Therefore, the bus travels 48 miles in 60 minutes.

Answer 2

A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:
rate = 36 miles / 45 min = 0.8 miles per mindistance traveled = 0.8 miles per min ( 60 min ) = 48 miles
Hope this answers the question. Have a nice day.
