You can put this solution on YOUR website! Hans drove an average of 50 miles per hours for a trip that took 6 hours.
In the first four hours, he drove 47 miles every hours.
Determine the total distance he travelled and his average speed in the last 2 hours.
:
From the information given we can determine the total dist and dist at 47 mph
d = speed * time
6 * 50 = 300 mi total distance
4 * 47 = 188 mi at 47 mph
then
300 - 188 = 112 mi = dist in the last two hrs
:
s =
s = 56 mph during the last two hrs
;
:
Check this by finding the times + =
4 + 2 = 6
