Question

a man travelled 10 km in 50 minutes what is the speed ​

Answer 1

Answer:

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

50 mins = 50/60 = 5/6hrs

speed = 10/(5/6)

= 12km/hr

Answer 2

$distance \: covered \: = 10km \\ = 10000 \: metre \\ time \: taken = 50 \: minutes \\ = (50 \times 60) seconds \\ \\ speed = distance \div time \: taken \\ = 10000 \div 50 \times 60 \\ = 3.33m {s}^{ - 1}$

here is your answer

hope it helps
