Answer:
20.04 miles/hour
1 hour 29 minutes 49.2 seconds
Step-by-step explanation:
The record for the Boston Marathon's wheelchair division = 1 hour 18 minutes and 27 seconds.
converting to hours ( 1 + 18 ÷ 60 +27 ÷ 3600 ) = 1.3075 hrs.
Speed = [tex]\frac{Distance}{Time}[/tex]
= [tex]\frac{26.2}{1.3075}[/tex]
= 20.04 miles per hour
At this speed 30-mile race will be cover = [tex]\frac{\text{30miles}}{\text{20.04hours}}[/tex] ≈ 1.497 hours
1.497 hours = 1 hour 29.82 minutes [multiply 0.497 by 60 to find the number of minutes]
1 hour 29.82 minutes = 1 hour 29 minutes and 49.2 seconds [multiply 0.82 by 60 to get seconds]
Average speed of the record winner is 20.04 miles per hour.
It will take 1 hour 29 minutes 49.2 seconds to complete a 30-mile race.
