Answer:
Step-by-step explanation:
Step one:
given data
time takent= 3.5hours
distance = 60.9miles
the average speed is given as
Average speed= distance/time
Average speed= 60.9/3.5
Average speed= 17.4mph
Step two:
we are told that the speed was actually maintained, so we used the previous value obatained for the following computation
For a time taken as 1 hour, the distance will be
distance= average speed * time
distance= 17.4*1
distance= 17.4 miles
