Question

In an average of 65 minutes if a train stops at three stations for two minutes each and the distance is 115 miles between stops what is the average speed

Answer 1

Answer:

117mph

Step-by-step explanation:

Given that

Total number of stations= 3

Total average time of journey of train = 65

total stop time at three stations = 3×2 =6 min

Total distance between stops = 115 miles

as we can see

Total time train was travelling = 65- 6 =59 min

so, average speed of train can be calculated as:

Average Speed = $\frac{Distance -travelled-between -stations}{Total-time-the-train-travelled}$

Average Speed = $\frac{115}{59} =1.95 miles/minute$

To convert this speed into miles per hour (mph) multiply the above speed by 60

Average speed = 60×1.95 =117 mph

So the average speed of train is 117mph.
