Answer:

79 minutes

Step-by-step explanation:

A plane is travelling at 180 meters per seconds

Convert to km/hr

180× 18/5

= 648 km/hr

Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is

= 1/648 × 800

= 1 hour 19 minutes

Conver the time to full minutes

60 minutes = 1 hour

= 60+19

= 79 minutes

Hence the minutes required for the plane to travel 800km is 79 minutes

Here goes another question: 4/5%9/10 and please if you can with procces

When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.

The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.

for example, the reciprocal of 9/10 is 10/9

Knowing this information 4/5÷9/10 is the same as 4/5×10/9

Now we can solve...

\frac{4}{5} * \frac{10}{9} = \frac{40}{45} = \frac{8}{9}

Answer= 8/9

If m &lt; c = 147 , determine m &lt; e <br><br> a) 147 <br> b) 57 <br> c) 33 <br> d) 180
sveticcg [70]

Answer:

c) 33

Step-by-step explanation:

We can calculate supplementary angles by subtracting the given angle from 180°. To find the other angle (in your case, ∠e), use the ∠y = 180° – ∠x where ∠x is the given angle.

Shawn and Ellie are construction workers. Shawn can complete a concrete job in 5 hours, while Ellie can complete it in 7 hours.
eimsori [14]

Step-by-step explanation:

We generally assume that when multiple resources are put on a job, the completion rate is the sum of the completion rates of the different resources. Rate is generally measured in units per time. Here, the appropriate "unit" is "job".

Step 1 is convert the hours per job to a rate in terms of jobs per hour.

... Shawn can complete 1/5 job per hour.

... Ellie can complete 1/7 job per hour.

Step 2 is to add the rates to get the total rate when both resources are applied.

... (1/5 job/h) + (1/7 job/h) = (7/35 +5/35) job/h = 12/35 job/h

Step 3 is to convert that rate back to the time require to complete one job. We can divide the work to be done (1 job) by the rate at which it is done in order to find the time required.

... (1 job)/(12/35 job/h) = 35/12 h = 2 11/12 hours = 2 hours 55 minutes

The foreman is incorrect.

_____

<em>Comment on the solution</em>

The time when workers work together will always be between the longest time divided by the number of workers (7/2 = 3.5 hours here) and the shortest time divided by the number of workers (5/2 = 2.5 hours here). Our answer of 2.92 hours is in that range.

The foreman should know better. (If s/he were to divide the average completion time (6 h) by the number of workers (2), s/he would have a guess of 3 hours—closer, but still incorrect.)
