Question

Α man
can
over 17/2 km
in 5 hours. find his speed
in (a) m/min
m (b) m/sec.​

Answer 1

Step-by-step explanation:

0.36 m/m. B) 0.0006 m/s. Step-by-step explanation: Okay so time taken = 5 hours = 300 min or 18000 sec.

Answer 2

Speed is $\frac{85}{3}$  m/min in case of (a) and in case of (b), it is $\frac{17}{56}$ m/sec

Step-by-step explanation:  

Given data;

Distance (D) = $\frac{17}{2}$  Km = $\frac{17}{2}$ × 1000 m  

Time (T) = 5 hours = 5 ×  60 min = 5 ×  60 × 60 sec

Formula used;

Speed (S) = $\frac{Distance(D)}{Time(T)}$

Step 1 - Speed in m/min

for this case Distance should be in m and Time is in min such as,

D = $\frac{17000}{2}$  m  and  T = 300 min  

and Speed become,  

S  = $\frac{D}{T}$

    = $\frac{\frac{17000}{2} }{300}$

     = $\frac{85}{3}$  m/min  

Step 2- Speed in m/sec

For this case Distance should be in m and time in sec such as,

D =  $\frac{17000}{2}$  m and T = 18000 sec

and Speed become,

S = $\frac{\frac{17000}{2} }{18000}$

   =  $\frac{17}{36}$ m/sec

Speed is $\frac{85}{3}$  m/min and   $\frac{17}{36}$ m/sec.
