Question

A dragonfly flies 7/8 of a mile in 3/10 of an hour. At this rate, how far can the dragonfly fly in 1 hour?

Answer 1

Answer:The dragon fly can fly 35/12 miles

Step-by-step explanation:

Speed   =distance / time

If the distance A dragonfly flies 7/8 of a mile

And

Time  =3/10 of an hour.  

Speed =7/ 8 ÷3/10 =7/ 8 x 10/3 =70/24  reducing to lowest term becomes 35/12 miles / hour

Now when the dragon fly flies in 1 hour, its distance covered becomes

Speed   =distance / time

35/12 miles / hour=distance / 1

distance =35/12 miles
