A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally. How long will each k

Harman [31]

Answer:

Each knight will guard 288 minutes in one day.

Step-by-step explanation:

Given:

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally.

Now, to find the minutes will each night spend on guard duty in one day.

As, in 1 hour there are 60 minutes.

Thus, in 24 hour there are 60 × 24 = 1440 minutes.

Total minutes for guarding = 1440 minutes.

So, there are knights ordered for guarding are = 5.

And each day's guard duty equally.

Now, to get the minutes will each night spend on guard duty in one day we divide the total minutes for guarding by number of knights that is 5:

$1440\div5$

$=288\ minutes.$

Therefore, each knight will guard 288 minutes in one day.

You need to rent a truck for one day to move equipment. FAST Movers will rent the truck for $39.95 per day with unlimited mileag

Gekata [30.6K]

Hi there! :)

Answer:

Cost with FAST Movers: $39.95

Cost with SPEEDY Movers: $38.70

⇒ SO, it would be cheaper to go with the SPEEDY Movers.

Step-by-step explanation:

Since the FAST Movers ask for 1 price only and don't charge for mileage, the cost with the FAST Movers would be $39.95.

For the SPEEDY Movers, they ask for a flat rate of $29.95 and charge $0.35 per mile for all miles over 75 miles.

Since you traveled 100 miles, they would charge you for the extra 25 miles (100 - 75 = 25).

They charge $0.35 for 1 mile, so in order to know how much they charge for 25 miles, you'll need to multiply "0.35" by "25" :

0.35 × 25 = $8.75

So for the SPEEDY Movers, you would be charged $29.95 plus $8.75 for the extra miles:

29.95 + 8.75 = $38.70 ⇒ The cost with the SPEEDY Movers

There you go! I really hope this helped, if there's anything just let me know! :)

At an automobile factory, 1849 parts are made in 4 hours. What is the average rate at which parts are made per hour?

Rudiy27

Just divide "1849 parts" by "4 hours:" the average rate is 1849/4 parts/hour,

or 1849 parts/ 4 hours, or 462.25 parts/hour, or (rounded off) 462 parts/hour.
