Question

a bike can cover a certain distance with a Speed of 56km h-¹ in 6 hours . what should be the speed of the bike if the same distance is to be covered in 8 hours​

Answer 1

Answer:

$2 + 2$

$4 - 4$

Answer 2

Speed = 56 * 1000 / 3600 m/s

            = 15.56m/s

Time    = 6 * 3600

           = 216000 sec

Distance = Speed * Time

               = 15.56 * 216000

                 =3360960m

Now ,

Distance =  3360960

time = 8*3600

       = 288000

speed = distance / time

           = 3360960 / 288000

           = 11.67

The speed should be 11.67m/s
