1) 1hour 10minutes =
hours,
50 minutes =
hours
2) speed of plane against the wind =
3) speed of plane on the the wind =
4) (336-240):2=48miles/hours - speed of wind
5)336-48=288miles/hours - plane's speed <span>in still air
Answer: speed of wind is 48 miles/hours, speed of </span>plane in still air is 288 miles/hours
Answer:
The distance would be 64 and 4 miles per hour would be its average speed.
Step-by-step explanation:
On a number line 34 to 0 is 34 points. And 0 to -34 is also 34 points. Add them together and you will get the distance. To find the average speed divide the distance by the time it took to cover that distance in this case 17 minutes and you will find the average speed of the dot.
Both are not earning different salaries.
If a study determines the difference in average salary for subpopulations of mechanical engineers and civil engineers is NOT significant, then the subpopulations of mechanical and civil engineers are not earning different salaries.
Study determines that there is not any significant study so thats why both are not earning.

Answer:
a + 20 = 7*12 (multiplied both sides by 12)
a + 20 = 84 (calculated 7*12)
a = 84 - 20 (subtracted 20 on both sides)
a = 64 (calculated 84-20)
Answer: 25 Hours
Step-by-step explanation: Multiply 4 until you get 100 and that value is your answer.
