) I went from my house to a playground, 300 metres away in 10 minutes. I ran back and
reached in 2 minutes. What was my average
speed? give answer fast!

v = 0.834 m/s or 3 km/h

Step-by-step explanation:

Given that,

Distance between house and playground is 300 meters

If you went 300  metres away in 10 minutes and ran back and  reached in 2 minutes, it means total distance covered by you during whole journey is 300 m + 300 m = 600 m

Total time, t = 10 min + 2 min = 12 min = 720 seconds

Total distance covered divided by total time gives average speed. So,

or

v = 3 km/h

So, the average speed is 0.834 m/s or 3 km/h.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
