A. convert 1 hour, 18 mins, 27 secs to hours.
1+(18÷60)+27÷3,600)=1.3075 hours 
26.2 miles in 1.3075= 26.2 miles / 1.3075 hr
= 26.2÷1.3075/1.3075÷1.3075
 (divide the numerator and the denominator by 1.3075)
= 20.04/1
B. divide the distance by the average speed to find the time. 
30 miles
---------------
20.04 mph ( which equals 1.497 hours)
so it would take 1.5 hours
Hope this helped!
