Answer: 120 ft/sec
Step-by-step explanation:
In this type of relative motion,
We have to cover both the length of the train and the field and then divide it by the speed of the train.
Total distance (s) = 700ft + 500ft
= 1200ft
Time taken (t) = 10 seconds
Therefore, speed of train is given by,
v = s/t
= 1200ft / 10 sec
= 120 ft/sec.
