Question

1) Calculate the speed for a car that went a distance of 125 kilometers in 2 hours time.

2) A baseball is thrown a distance of 60 meters. What is its speed if it takes 0.5 seconds to cover the distance?

3) How much time does it take for a bird flying at a speed of 45 kilometers per hour to travel a distance of 1,800
kilometers?

Answer 1

1. speed of the car=125/2km/hr
2.speed of baseball=60×2=120m/s
3. time taken=1800/45hr=40hr

Answer 2

Question 1)

Car travelled 125 km in 2 hours time .

So, speed will be :

$\rm \: v = \dfrac{distance}{time}$

$\rm \implies v = \dfrac{125}{2}$

$\rm \implies v = 62.5 \: km \: {hr}^{ - 1}$

Question 2)

Ball travels 60 metres in 0.5 seconds.

So, speed of ball will be :

$\rm \: v = \dfrac{distance}{time}$

$\rm \implies v = \dfrac{60}{0.5}$

$\rm \implies v = 120 \: m {s}^{ - 1}$

Question 3)

Bird travels 1800 km with 45 km/hr speed.

So, time taken is :

$\rm \: time = \dfrac{distance}{speed}$

$\rm \implies \: t = \dfrac{1800}{45}$

$\rm \implies \: t = 40 \: hours$
