Question

In 100 meter race zahid cover it in 5.8 minutes while iqbal cover it in 4.8 minutes find the ratio between thier time.​

Answer 1

Solution:

Time taken by Zahid = 5.8 min

Time taken by Iqbal = 4.8 min

Ratio between timings = 5.8, 4.8

= 5.8 : 4.8 (× by 10)

= 58 : 48

= 29 : 24

Ratio between timings = 29 : 24 (ans)

Answer 2

Its not 19 its 18.96 meter.

Lets say distance is 100 mtr

Time taken by A = 60 second

Since A defeated B by 10 meter.. so when A was crossing the win line B covered(100-10 = 90 meter).

So B took 60 second to cover 90 meter.

Time taken by B to reach win line or time taken by B to cover 100 meter:

(60/90)*100 = 66.6 second

So B took 66.6 to reach winning line.

So while B was crossing win line on 66.6th second C covered 90 meter(100-90 second)

Time taken by C to reach win line or time taken by C to cover 100 meter:

(66.6/90)*100 = 74.04 second

Since all player are running with same speed.

Now we have time taken my each player to cover 100 meter.

Distance with which A defeated C is equal

(Distance of A in 60 second) - (distance of C in 60 second) = 100 - (100*60/74.04) = 100-81.03 = 18.96 meter

So exact answer is 18.96 meter.
