Question

if a man walks 16 km in 5 hours how long would he take to walk 11.2 km​

Answer 1

Answer:

3.5 hours.

Step-by-step explanation:

A man walks 16 km in 5 hrs

this implies that speed of man = 16/5 km/h

Therefore time is taken by a man to cover a distance of 11.2 km = 11.2/ (16/5) = 3.5 hrs

(speed=distance/time

time=distance/speed.)

Answer 2

Answer:

let time taken to complete a distance of hrs=11.2km

distance= 16 km , 11.2km

time = 5 hrs , x

since, this is case of direct varation

(now do cross multiply)

16×x = 5×11.2

x = 5×11.2/16

x = 3.5(answer)
