Question

a car is moving at a speed of 54 km / hour .how much distance will the car cover in 10 minutes.​

Answer 1

Given:-

• Speed ,s = 54km/h
• Time ,t = 10min

To Find:-

• Distance covered by car ,d

Solution:-

According to the Question

we have to calculate the distance covered by car .

Firstly we change the speed into m/s by multiplying 5/18 .

$:\implies$ s = 54×5/18

$:\implies$ s = 3×5

$:\implies$ s = 15m/s

Now, converting the time into second

⠀⠀⠀⠀⠀⠀⠀⠀$:\implies$ 1min = 60 s

$:\implies$ 10min = 60×10 = 600s

Calculating the distance covered by car .

• d = st

where,

• d denote distance
• s denote speed
• t denote time taken

Substitute the value we get

$:\implies$ d = 15×600

$:\implies$ d = 9000m

$:\implies$ d = 9000/1000 km

⠀⠀⠀⠀⠀⠀⠀⠀$:\implies$ d = 9km

• Hence, the distance covered by the car is 9 kilometres.
