A man crosses a 600 m bridge in 5 minutes. What is his speed in km per hour?

$\large{\underline{\underline{\maltese{\orange{\pmb{\sf{ \; Given \; :- }}}}}}}$

• DISTANCE = 600 m = 0•6 km

• TIME = 5 mins = 0•083 hrs

$\large{\underline{\underline{\maltese{\orange{\pmb{\sf{ \; To \: Find \; :- }}}}}}}$

• SPEED

$\large{\underline{\underline{\maltese{\orange{\pmb{\sf{ \; Formula \: Used \; :- }}}}}}}$

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

$\large{\underline{\underline{\maltese{\orange{\pmb{\sf{ \; Solution \; :- }}}}}}}$

$\large = > \frac{6 \times 1000}{83 \times 10}$

$\large = > \frac{6000}{830}$

$\large = > \cancel\frac{6000}{830}$

$\large = > 7.2$

$\large{\underline{\underline{\maltese{\orange{\pmb{\sf{ \; Answer \; :- }}}}}}}$

The speed of the man is :-

• 7•2 km/h

Answer 2

Answer:

Distance- 600m

Time- 5min

Speed- Distance/time

= 600/5

= 120m/min

Man's speed in km/hr= 120/1000 × 1/60

= 120×60/1000

= 7200/1000

= 7.2 km/hr
