Question

a bird flies at a speed of 250km/h if it covers a distance of 10,000m, calculate the time it took to complete the journey

Answer 1

Solution

Speed of a bird = 250km/h.

Distance covered by a bird = 10,000m

Converting distance into km

1km = 1000m

1000m = 1km

10000 = 10000÷1000 = 10km.

Calculating Time Taken

$\sf{Speed=\dfrac{Distance}{Time} } \\\ \: \sf{\therefore \: Time= \frac{Distance}{Speed}}$

$\sf{= \cancel\dfrac{10}{250} = \dfrac{1}{25} = 0.04h.}$

Hence, time is 0.04hours or 2.4minutes(0.04×60).

Answer 2

$\huge\bigstar\mathbb\red{soLuTiOn}\bigstar$

Speed of a bird = 250km/h.

Distance covered by a bird = 10,000m

Converting distance into km

1km = 1000m

1000m = 1km

10000 = 10000 ÷ 1000 = 10km.

Calculating Time Taken

Hence, time is 0.04 hours or 2.4 minutes (0.04×60) .
