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
