2520 stones which will cost £6300

Step-by-step explanation:

First find area of path:

630 x 120 = 75600 cm²

then find how many stones will be needed:

75600/30 = 2520

then find out the total cost:

2520 x 2.5 = £6300

Hope this helps!

£125

Step-by-step explanation:

First, find perimeter.

630 + 630 + 120 + 120 = 1500

Divide by stone width.

1500 / 30 = 50

Multiply by the cost.

50 x 2.5 = 125

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
