So, we know both faucets open, can do the whole job in 6minutes
ok, how much has the faster cold water faucet done in 1minute then?
well, let's say the the rate of speed of the cold water faucet is "c", so in 1minute it has done 1/c of the whole work
now, we know the hot water faucet is slower, it takes it 3 times as long, that means is 1/3 the speed of the cold water faucet, so, how much does the hot water faucet do in 1min? well, we know is 1/3 fast as the cold one, the cold one is 1/c, what's 1/3 of 1/c? well, 1/3 * 1/c
now, we know they both added together, can do the whole job in 6 minutes, so in 1minute, they've done 1/6 of the job then
thus

Answer:
The speed of tortoise is 2 miles per hour and
The speed of hare is 11 miles per hour
Step-by-step explanation:
Given as :
The distance cover by tortoise = miles
The Time taken by tortoise to cover distance = hour
So, The speed of the tortoise is =
I.e The speed of the tortoise =
∴ The speed of the tortoise = 2 miles per hour
Again ,
The distance cover by hare = miles
The Time taken by hare to cover distance = hour
So, The speed of the hare =
I.e The speed of the hare =
∴ The speed of the hare = 11 miles per hour
Hence The speed of tortoise is 2 miles per hour and
The speed of hare is 11 miles per hour . Answer
