Question

A man run at the speed of 15 km per hour. How much time will he take to cover 750 m ?

Answer 1

ANSWER:
S=15km/h*5/18=75/18m/s.
D=75m.
T=D/S.
T=75÷(75/18).
T=18s.

Answer 2

Answer:

Time he will take to cover 750 m = 3 min hours.

Step-by-step explanation:

Speed = 15 km per hour

Distance = 750 meters =

$\frac{750}{1000}km \: \frac{3}{4}km$

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

= $( \frac{3}{4} \div 15)hr$

= $\frac{3}{4} \times \frac{1}{15}hr$

= $\frac{1}{20}hr$

= $\frac{1}{20} \times 60min = 3 \: min$
