Question

train travel 32 km in 12 mints. calculate speed of train?​

Answer 1

Answer:

the required speed is 160km/ hour

Step-by-step explanation:

According to the problem,

time(min) distance(km)

12 32

60 X (let)

(60 min = 1 hr)

since, the speed and time of the train are directly proprotional, the direct ratio is,

12:60::32:X

=> 12/60 = 32/X

=> 12X = 32×60

=> X = 32×60/12

=> X = 160

ans) the required speed is 160km/hr

Answer 2

Answer: the required speed is 160km/ hour

Step-by-step explanation: According to the problem,

time(min) distance(km)

12 32

60 X (let)

(60 min = 1 hr)

since, the speed and time of the train are directly proprotional, the direct ratio is,

12:60::32:X

=> 12/60 = 32/X

=> 12X = 32×60

=> X = 32×60/12

=> X = 160

ans) the required speed is 160km/hr
