Question

11. If a man walks 16 km in 5 hours, how long would he take to walk 11.2 kr​

Answer 1

let the distance be x

16x = 5

11.2x= ?

16x = 5

x = 16/5

x = 3.2

so distance covered in 1 hour = 3.2 hrs

therefore if distance covered is 11.2 km

then,

11.2 / 3.2 = 3.5 hrs

Answer 2

Step-by-step explanation:

given distance D= 16km in time t = 5hours

applying elimination method

if he take 5hours to travel 16km, his speed will be,

speed = distance/time

= 16/5 = 3.2km/hour

now 16km he takes 5 hours

for 11.2km let t' be the time taken then

t' = distance /speed = 11.2/3.2 = 3.5 hours

so he will take 3.5 hours to travel 11.2 km
