Alekssandra [29.7K]

Answer:

<em>58.7 ft/sec</em>

Step-by-step explanation:

The train traveled half a mile.

1 mile = 5280 ft

0.5 mile = 0.5 * 5280 ft = 2640 ft

A time from 10 sec to 55 sec is 55 sec - 10 sec = 45 seconds.

2640 ft in 45 seconds

speed = distance/time

speed = 2640 ft / 45 sec = 58.6666... ft/sec

Answer: speed = 58.7 ft/sec
