Answer:

72 000

Explanation:

1km = 1000m

72km / h

72 x 1000 = 72 000

Explanation:

It is said that the bus moves with the speed of 72 km/hr.

It means that the bus covers 72 km in 1 hour.

so,

It covers 72 * 1000 m = 72000 m in one hour.

Hope it helps :)

An object moves with a speed of 30 km/h for 15 minutes and then with a speed of 60km/h for the next 15 minutes. Find the total d

Finger [1]

Answer:

Total distance = 22.5 kilometers

Explanation:

Let the first distance be A.

Let the second distance be B

Given the following data;

Speed A = 30km/h

Time A = 15 minutes to hours = 15/60 = 0.25 hour

Speed B = 60km/h

Time B = 15 minutes to hours = 15/60 = 0.25 hour

Now, to find the respective distance traveled;

Distance A = speed A * time A

Distance A = 30 * 0.25

Distance A = 7.5 km

Distance B = speed B * time B

Distance B = 60 * 0.25

Distance B = 15 km

Next, we calculate the total distance traveled;

Total distance = Distance A + distance B

Total distance = 7.5 + 15

Total distance = 22.5 kilometers.

Therefore, the total distance covered by the object is 22.5 kilometers.

Canada geese migrate essentially along a north–south direction for well over a thousand kilo-meters in some cases, traveling at

kotykmax [81]

Answer:

a) 66.4 relative to the west in the south-west direction

b) 5.455 hours

Explanation:

a)If the wind is blowing east-ward at a speed of 40km/h, then the west component of the geese velocity must be 40km/h in order to counter balance it. Geese should be flying south-west at an angle of

$cos(\alpha) = 40 / 100 = 0.4$

$\alpha = cos^{-1}(0.4) = 1.16 rad = 180\frac{1.16}{\pi} = 66.4^0$ relative to the West

b) The south-component of the geese velocity is

$100sin(\alpha) = 100sin(66.4^0) = 91.65 km/h$

The time it would take for the geese to cover 500km at this rate is

t = 500 / 91.65 = 5.455 hours
