Answer 2

Answer:

Conversion of  $315$ km/h to meter /sec. is  $87. 5 \ m /sec$ .

Step-by-step explanation:

To convert : $315$ km/h to meter /sec.

Solution :

• According to question we have to convert  $315$ km/h to meter /sec.
• As we know, $1 (kilometer/hour )=1000( meter ) / 3600( second )$  which can also be expressed as $1 (kilometer/hour) =\frac{5}{18} ( meter/second)$ which is simplified form.
• Therefore, to convert we directly multiply given value of speed by the fraction $\frac{5}{18}$
• Hence, we get $315 km/h =315 \times \frac{5}{18}\ ( m/sec)$  

                                                 $=17.5\times 5 \ ( m/ sec )\\\\= 87.5\ (m / sec )$
