Question

3. A small airplane flew 104 miles in 50

minutes. At this rate, how many miles can it
fly in one hour? (50 minutes = 5/6 hour)
(Example 1)

Answer 1

124.8 minutes is the answer. You put 104/50=2.08. So, 2.08x60=124.8.

Answer 2

Answer: 124.8 miles

Explanation:

We know that if the rate of change of distance with respect to time remains constant, then the distance and time are proportional .

Given : A small airplane flew 104 miles in 50 minutes.

Let x be the distance traveled in 1 hour

Also, it is given that
`\text{50 minutes}= (5)/(6)\text{ hour}`

Then we have the following proportional equation:-

`(x)/(1)=(104)/((5)/(6))\\\\\Rightarrow\ x=(104*6)/(5)=124.8\text{ miles}`

Hence, it can fly 124.8 miles in an hour.
