Answer 2

$\displaystyle \sf \frac{13}{36} \: \:m/s = 1.3 \: \: kmph$

Given :

13/36 m/s

To find :

Convert the 13/36 m/s into kilometers per hour

• 1.2 kmph

• 1.3 kmph

• 1.4 kmph

• 1.5 kmph

• None of these

Solution :

Step 1 of 2 :

Write down the given data

Here we have to Convert the 13/36 m/s into kilometers per hour

Step 2 of 2 :

Choose the correct option

We know that , 1 km = 1000 m

1 hour = 3600 sec

Thus we get

$\displaystyle \sf \frac{13}{36} \: \:m/s$

$\displaystyle \sf = \frac{ \dfrac{13}{1000} }{ \dfrac{36}{3600} } \: \:\: \: kmph$

$\displaystyle \sf = \frac{13}{1000} \times \frac{3600}{36} \: \:\: \: kmph$

$\displaystyle \sf = \frac{13}{10} \: \:\: \: kmph$

$\displaystyle \sf = 1.3 \: \:\: \: kmph$

Hence the correct option is 1.3 kmph
