Question

The expression rt can be used to find the distance traveled by an object that has an average speed of r overtime t. How many miles will a hot air balloon travel in 2.2 hours if it travels at an average speed of 12.5 miles per hour

Answer 1

`d = 12.5 (mi)/(hr) *2.2 hr = 27.5 mi`

So then after 2.2 hours with an average speed of 12.5 mi/hr the hot air ballon will travel 27.5 mi

Explanation:

For this problem we know that the distance traveled by an object is given by:

`d = rt` (1)

Where d is the distance r the average speed and t the time.

From the info given we know that
`t = 2.2 hours` and
`r= 12.5 (mi)/(hr)`

And replacing into formula (1) we got:

`d = 12.5 (mi)/(hr) *2.2 hr = 27.5 mi`

So then after 2.2 hours with an average speed of 12.5 mi/hr the hot air ballon will travel 27.5 mi
