Question

a boy is running at a constant speed5/s. find the time taken to cover a distance of 80cm​

Answer 1

let the time taken by boy =x

the speed by boy = 5

the distance travelled by boy=80. cm

so time =distance/speed

time=80/5

time=16

there fore time taken by boy=16sec

Answer 2

Step-by-step explanation:

speed=5cm/s

distance =80cm

we know that distance =speed ×time

=>time =distance ÷speed

=80/5=16s

therefore time taken is 16sec
