Question

Find out the distance covered when speed is 960 km/hour and time is 4 hour

Answer 1

Answer:

3840 kms

Explanation:

960km/hour for 4 hours can be calculated as 960×4=3840

Answer 2

Answering according to ques.!

Provided that:

• Speed = 960 km/h
• Time taken = 4 hours

To calculate:

• The distance

Solution:

• Distance = 3840 km

Using concept:

• Formula to find distance

Using formula:

• ${\small{\underline{\boxed{\sf{Distance \: = Speed \times Time}}}}}$

Required solution:

$:\implies \sf Distance \: = Speed \times Time \\ \\ :\implies \sf Distance \: = 960 \times 4 \\ \\ :\implies \sf Distance \: = 3840 \: kilometres \\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$

Answering according to SI unit!

Provided that:

• Speed = 960 km/h
• Time taken = 4 hours

To calculate:

• The distance

Solution:

• Distance = 3839904 m

Using concepts:

• Formula to find distance
• Formula to convert kmph-mps
• Formula to convert hr into s

Using formulas:

• ${\small{\underline{\boxed{\sf{Distance \: = Speed \times Time}}}}}$

• ${\small{\underline{\boxed{\sf{1 \: hour \: = 3600 \: seconds}}}}}$

Required solution:

~ Firstly let us convert kmph into mps!

$:\implies \sf 960 \times \dfrac{5}{18} \\ \\ :\implies \sf \dfrac{4800}{18} \\ \\ :\implies \sf \cancel{\dfrac{4800}{18}} \\ \\ :\implies \sf 266.66 \: ms^{-1} \\ \\ {\pmb{\sf{Henceforth, \: converted!}}}$

~ Now let's convert hr into seconds!

$:\implies \sf 1 \: hour \: = 3600 \: seconds \\ \\ :\implies \sf 4 \: hours \: = 4 \times 3600 \: seconds \\ \\ :\implies \sf 4 \: hours \: = 14400 \: seconds \\ \\ {\pmb{\sf{Henceforth, \: converted!}}}$

~ Now let's calculate distance!

$:\implies \sf Distance \: = Speed \times Time \\ \\ :\implies \sf Distance \: = 266.66 \times 14400 \\ \\ :\implies \sf Distance \: = 3839904 \: metres \\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$
