Noor rode her bike two fifth mile in one twelfth hour. At this rate, how far would Noor ride her bike in 1 hour?
2 answers:
2/5 in 1/12 of an hour x in 1 hour So multiply 12 to both fractions 2/5 x 12 in 1/12 x 12 of an hour We get now: 24/5 in 1 hour or: 4 4/5 in 1 hour
First convert 1/12 of an hour to minutes 1 hr= 60 minutes
1/12 x 60= 5 minutes
ratio and proportion
2/5 / 5= x/60
cross multiply
5x= 24
x= 4 4/5 mi or 4.8 mi
