The tail of a 1-mile long train exits a tunnel exactly 3 minutes after the front of the train entered the tunnel. If the train i

igomit [66]

The tail of the train starts one mile from the mouth of the tunnel and it must travel that distance plus the length of the tunnel in 3 minutes.

Let t = tunnel length

t + 1 = distance the tail must travel in 3 minutes.

3 minutes = 1/20 hr

(t+1) miles / 60 m/hr = 1/20 hr

t + 1 = 60/20

t+1 = 3

Subtract 1 from each side:

t = 2

The tunnel is 2 miles long.

vredina [299]

Hi there!

Dimensions of rectangular room :-

• Length = 109 inches
• Breadth = 103 inches

Dimensions of square tiles :-

• Each side = 3 inches

It's known :-

No. of tiles = Area of rectangular room / Area of tile

No. of tiles = $\dfrac {109 × 103}{3}$

No. of tiles = $\dfrac {11227}{9}$

No. of tiles = 1,247

Hence,
Th' number of tiles required for the job is 1,247

~ Hope it helps!
