Question

A man complete 2.5km in 10minutes find speed

Answer 1

Answer:

Distance = 2.5 km = 25/10 km

Time = 10 min = 1/6 hr

Speed = Distance/Time = (25/10)/(1/6) = 15 km/hr

Answer 2

Answer:

$speed = \frac{distance}{time}$

so Distance= 2.5km

Time = 10 min or 10/60 hrs

$so \\ speed = \frac{distance }{time} \\ speed = 2.5 \div \frac{10}{60 } \\ = \frac{25}{10} \times \frac{60}{10} = 15km \: per \: hour$
