First take note the kite is traveling at 40 km/hr, but we want to know how far she traveled in 15 minutes.
First divide 60(total minutes in an hour) by 15
60/15=4
Now divide 40 by 4
40/4=10
So she will travel 10 km in 15 minutes.
5 metres
Explanation:
Work Done = Force x Distance
So Distance = Work done ÷ Force
= 35 ÷ 7.0
= 5 metres
