Question

Kunal cycles at a speed of 20 Km/hr and reaches school in 20 minutes. At what speed should he cycle so that he reaches school in 16 minutes?

Answer 1

Answer:

25 km/hr

Step-by-step explanation:

Given,

Kunal cycles at a speed of 20 Km/hr and reaches school in 20 minutes.

speed= distance travelled / time taken

20 km/hr=Distance/20 min

distance=20km/hr*20 min

At what speed should he cycle so that he reaches school in 16 minutes?

let speed be x km/hr

Distance=x km/hr*16mins

if the distance is same then,

20 km/hr*20/60=x km/hr*16/60

x km/hr=25km/hr
