Answer:

Step-by-step explanation:

250m/s = x m/min
250m/s = x min/ 60s
250•60 = 1500
The airplane will travel 1500m per minute
Answer:
The speed of the private airplane is 770 mph, the speed of the commercial airplane is 980 mph.
Step-by-step explanation:
Let x mph be the speed of private airplane. If the speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane, then the speed of commercial airplane is (x+210) mph.
It takes the commercial jet 1.1 hours for the flight, then it covered the distance of

It takes the private airplane 1.8 hours for the flight, then it covered the distance of

The distances are the same, so

The speed of the private airplane is 770 mph, the speed of the commercial airplane is 770 + 210 = 980 mph.
Answer:
There are 8 adults in the group.
Step-by-step explanation:
Let the number of adults in the group be 'x'.
Given:
Number of children = 1
Number of adults = 'x'
Cost for a ticket of adult = $9
Cost for a ticket of a child = $6
Total cost = $78
Total cost is equal to total cost of tickets of 'x' adults plus cost of ticket of 1 child.
Unit cost of 1 adult × Number of adults + cost of ticket of 1 child = Total cost
Framing in equation form, we get:

<u><em>Adding -6 on both sides, we get:</em></u>

<u><em>Dividing both sides by 9, we get:</em></u>

Therefore, there are 8 adults in the group.
