Team raise over run caned 15 3/4 miles in 2 1/4 hours. what was their averge rate in mile per hour.

The average rate in mile per hour = 7

Step-by-step explanation:

Given:

Team Rise Over Rune canoed = miles

Time taken to canoe = hours

To find the average rate in miles per hour.

Solution:

To find the average rate canoed by the team, we need to divide the total number of miles canoed by total time taken.

Average rate in miles per hour will be given as:

⇒

In order to divide mixed number, we need to first convert them to fraction.

So, we write the mixed numbers as fraction with same denominator and the numerator = product of the denominator and whole number added to numerator of the mixed number.

So we have,

Thus, the division can now be rewritten as:

⇒

Now, in order to divide fractions, we will reciprocate the divisor by replacing the division to multiplication.

⇒

Canceling the common terms.

⇒

⇒ miles per hour

Thus, average rate in mile per hour = 7

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
