Question

a student runs 200 metres in 40 sec. find (a) his speed (b) distance run by him in 15 sec. (c) time taken by him in running 3/10 k

Answer 1

Answer:

$1) \: speed = distance \div time$

$\: \: \: \: \: \: = 200 \div 40$

$\: \: \: \: \: \: \: \: = 5m \: per \: sec$

$2) \: distance = speed \times time$

$\: \: \: \: \: \: \: \: \: \: \: = 5 \times 15$

$\: \: \: \: \: \: \: \: = 75m$
