Question

if the speed of anil and barun are, 40m/sec and 40km/hr respectively. then the ratio of time taken to cover a certain distance​

Answer 1

Answer:

5:18

Step-by-step explanation:

Given,

if the speed of anil and barun are, 40m/sec and 40km/hr respectively.

Anil = 40 m/sec

convert to km/hr

40*(10/5)=144 km/hr

barun=40 km/hr

then the ratio of time taken to cover a certain distance​

let distance is 'd' for both cases

t1 and t2 is time taken by anil and barun

s1 and s2 is speed of anil and barun

Speed=Distance/time

time=Distance/speed

t1/t2=(d/s1)/(d/s2)

t1/t2=s2/s1

t1/t2=40/144

t1/t2=5/18

Answer 2

Given:

Speed of Anil = 40 m/s

Speed of Barun = 40 km/hr

To find:

The ratio of time taken to cover a certain distance.

Solution:

First we need to convert both the speeds in the same unit.

Speed of Barun = 40* 18/5 = 144 km/hr

Time taken by Anil to cover a distance d = d/ 144 sec

Time taken by Barun to cover a distance d = d/ 40 sec

Ratio of their time taken = (d/144) / (d/40)

= 40 / 140 = 5: 18

Therefore the ratio of their time taken to cover a certain distance will be 5 : 18.
