Question

a man can cover17 1/2 km in 5 hours. find his speed in a. m/min andm/sec​

Answer 1

$\huge\underline\blue{\sf Answer}$

$\large\red{\boxed{\sf v=58.3m/min }}$

$\large\red{\boxed{\sf v=0.972m/s }}$

$\huge\underline\blue{\sf Solution:}$

$\large\underline\pink{\sf Given: }$

• Distance (s) = 17.5 km

• Time (t) = 5 hours

$\large\underline\pink{\sf To\:Find: }$

• Speed (v) = ? [ in m/min and m/sec

━━━━━━━━━━━━━━━━━━━━━━━━━

Convert "km" into "m"

$\large\implies{\sf s= 17.5km}$

$\large\implies{\sf s=17.5×1000 }$

$\large\implies{\sf s=17500 m}$

Convert "hours" into "minute" and "seconds"

$\large\implies{\sf t= 5 h}$

$\large\implies{\sf t=5×60}$

$\large\implies{\sf t=300 min }$

$\large\implies{\sf t=300×60}$

$\large\implies{\sf t=18000sec }$

We know that :

$\large{\boxed{\sf Speed={\frac{Distance}{Time}} }}$

$\large\implies{\sf v={\frac{17500}{300}}}$

$\huge\red{♡}$$\large\red{\boxed{\sf v=58.3m/min }}$

$\large\implies{\sf v={\frac{17500}{18000}}}$

$\huge\red{♡}$$\large\red{\boxed{\sf v=0.972m/s }}$

Answer 2

$\huge{\boxed{\boxed{\mathfrak{\pink{AnSweR:-}}}}}$

${\bold{\underline{\underline{Given:-}}}}$

•Distance = 17.5km

•Time =5hours

${\bold{\underline{\underline{To \: find :-}}}}$

•speed = ❓[measures in m/s]

${\bold{\underline{\underline{Step-by-step-explanation:-}}}}$

✏ first of all Convert distance into metre....

$\to\ s=17.5km \\ \\ \to\ s= 17.5 x 1000 \\ \\ \to\ 17500m$

✏Now,convert Time into seconds

$\to\ Time=5hours \\ \\ \to\ 5 \times\ 60 =300 \\ \\ \to\ 300 \times\ 60 \\ \\ \to\ 18000seconds$

We know that ,

$\huge\ Speed =\frac {Distance}{Time} \\ \\ \to\frac {17500}{300} \\ \\ \to\ Speed =58.3m/min.$

Now,Speed in seconds

$\to\ \frac {17500}{18000} \\ \\ \to\ Speed = 0.972m/s$
