The average speed is 25 mph during the 10.16 seconds, so the distance in miles is
25 miles/hour * 10.16 sec * 1/3600 hour/sec
= 0.070555556
Same answer as Helmut's but much easier. There is no need to compute the acceleration. Janus used my method of multiplying by half the final velocity but seems to have forgotten about the .16 seconds, so his answer is close but not exact.

50 mph means 80kmph. i means 80.000 meters per hour. its 22 meters per sec. so 22 x 10 = 220 but the graph is triangular so we have to divide it in two then its 110 meters... your answer is 110 meters

v = at
a = (50mph)(1hr/3600sec)/(10.16 sec)
s = (1/2)at^2
s = (1/2)(50mph)(1hr/3600sec)(10.16 sec)^2/(10.16 sec)
s = 0.071 mi
s = 372.5 ft

0.01388~9 of a mile
(0.013888888888888888888888888888889)
If I'm not mistaken.
