Question

Ahmed is moving in his car with a speed of 45 km /hr how much distance will he cover in 1 min and 1second

Answer 1

$\bigstar$ Answer:

$\checkmark$ Given:

Speed (v) = 45 km/hr

$\checkmark$ To Find:

Distance Covered in

• 1 Minute
• 1 Second

$\checkmark$ Solution:

We know that,

Formula:

$\green{\boxed{\rm Speed(v)=\dfrac{distance(d)}{time(t)}}}$

Given that,

$\star$ d = 45 km

⇒ d = 45,000 m

$\star$ t = 1 hour = 60 minutes = 60 x 60 seconds

⇒ t = 3600 seconds

Substituting the above values in the given formula,

We get,

$\implies \rm Speed(v)=\dfrac{45 \times 1000m}{60 \times 60s}$

$\implies \rm Speed\;(v)=12.5 \;m/s$

$\red{\boxed{\boxed{\rm v=12.5\;m/s}}}$

According to the Question,

We are asked to find the Distance covered in

• 1 Minute
• 1 Second

Hence,

Using the Formula Used Above to Find (v)

(With Small rearrangement)

$\pink{\boxed{\rm d=v \times t}}$

• Distance Covered in 1 Minute

v = 12.5 m/s

t = 60 seconds

Hence,

$\blue{\implies \rm d=12.5 \times 60\;\;m}$

$\blue{\implies \rm d=750\;\;m}$

• Distance Covered in 1 Second

v = 12.5 m/s

t = 1 second

Hence,

$\orange{\implies \rm d=12.5 \times 1\;\;m}$

$\orange{\implies \rm d=12.5 \;\;m}$

Hence,

Finally,

Distances Covered in

1 Minute is 750 m

1 Second is 12.5 m
