Question

convert 105 m per. minute into km per hour answer step by step​

Answer 1

Answer:

Speed = 105 m/sec

Time = 1 hour = (60 × 60) seconds = 3600 sec

.°. Distance convert in 1 hour = (speed×time)

= (105 × 3600) m

$= 105 \times \frac{3600}{1000} km \\ = \: 105 \times \frac{18}{5} km \: = 378 \: km$

Step-by-step explanation:

Thus, the distance convered in 1 hour = 378 km

.°. Required speed = 378 km/hr

Hence,105 m/sec = 378 km/hr.

Rule : To convert m/sec into km/hr , multiply the speed with 18/5.

Thus,10 m/sec = 10 times of 18/5 km/hr = 36 km/hr.
