Question

A cycle takes 2 hrs to cover a distance of 24 km. If its speed is increased by 4km /hr.
How long will it take to cover the same distance ?

Answer 1

Answer:

let Distance be D .speed be s

T=2hr

D=24km

s=D/T

s=24/2

s=12km/hr......

so according to the question speed is increased by 4km/hr.

so ..now .speed is 12

12+4(km/hr)

16km/hr

D=s×t

D=16×2.

D=32km/hr.................

if you have understood the answer then ONLY mark my answer as BRAINLIEST....

Answer 2

Speed=24/2=12kmh
New speed=12 + 4=16km/hr
Therefore
Time=distance/speed
T=24/16
T=1.5hr or 1hr and 30 mins
