Question

10. A train covers the distance between two stations which are 11 km apart in 12 minutes. At what
rate per hour is it travelling?​

Answer 1

Answer: approximately 14 m/s.

Step-by-step explanation:

Time = 12 minutes = 12 *60 = 720 seconds

Distance = 11 km = 11 * 1000 m = 11000 m

Speed = distance / time = 11000/720 = 13.89 m/s.

Answer 2

Answer:

55 km per hour

Step-by-step explanation:

distance travelled = 11km

time taken = 12 minutes

distance per minute = 11÷12

distance per hour = 11÷12*60= 55 km

so speed per hour = 55 km per hour
