Question

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

Answer 1

let the the distance covered by bike in six hours be x

bike travels for 6 house with a speed of 56 km/he

therefore

56×6=x × 8

therefore x= (56×6)÷8

x=7×6

x=42

Answer 2

The bike speed and the time are direct variation.

A bike can cover a certain distance with a speed of

56km h-¹ in 6 hours.

To find the bike in the same distance if in same distance is to be at cover in 8 hours.

so, Let the speed be x to cover in 8 hours

:. 56×6 = x/8

=> x = 56×6/8 = 7 × 6

= 42 hrs.

so, we want 42 km h-¹ speed to cover in 8 hrs.

it will can help most I think ..
