<h2><u>
Answer:</u></h2>
Nathan walks a total of <u>4.375 miles</u>
<h2><u>
Step-by-step explanation:</u></h2>
- The equation for distance is <u>speed = distance ÷ time</u>
- Reaarange the equation to make distance the subject:
<em>(multiply both sides by time)</em>
<em> </em><u><em>Distance = Speed × Time</em></u>
- Finally, substitute the numbers into the equation and solve:
Distance = 2.5 × 1.75 = <u>4.375 miles</u>
The average speed of the whole journey of car based mentioned speeds is 48 km/hr.
The average speed is calculated by the formula -
average speed = total distance covered ÷ total time taken. The total distance covered is sum of distance of first and return journey. Total distance covered = 100 + 100
Performing addition
Total distance covered = 200 kilometres
Now total time taken = time taken on first journey + time taken for return journey
Total time taken = distance/speed + distance/return speed
Total time taken = 100/60 + 100/40
Performing division
Total time taken = 5/3 + 5/2
Total time taken = 10 + 15/6
Total time taken = 25/6 hour
Average speed = 200/(25/6)
Average speed = (200×6)/25
Performing division and multiplication
Average speed = 48 km/hr

Answer:
We have the following system of equations:
(2) = x = 350-y . Replace x in equation (1 )
=> 5(350-y)+10y=2000 => y = 241
Replace y=241 in equation (2 ) => x = 350-241 = 109
the number of both children and adult tickets the theater can sell.
Children tickets : 109
Adult tickets : 241
