Answer:

289300 miles/72 hours * 1.60934 km/mile* 1 hour/3600 seconds = 1.48 km/second. Answer 6: To get average speed, we divide the total distance by the total time it takes to travel that distance. If we assume the distance to the moon is 238,900 miles then we divide by 72 hours to get roughly 3318 mph.

Step-by-step explanation:

Alinara [238K]

Answer:

85 degrees

Step-by-step explanation:

its really easy just make them equal to eachother and then solve

9x + 13 = 11x-3

-11x (subtract because 11x is positive)

-2x +13 = -3

-13 (subtract because 13 is positive)

-2x = -16

divide both sides by -2

x= 8

substitute 8 for the x's and you have your answer

It's 9 4/5 miles from Justin's house to the art museum the distance to the history museum is 9/10 this far
Leno4ka [110]
The history museum is less that 9 4/5 miles. 9/10 means that the 9 3/4 mile is broken up into 10 equal parts and the distance to the museum is only 9 of those parts. 9 3/4 (9.8) divided by 10 equals 98/100 (.98) 
98/100 x 9 = 882/100 or 8.82 

Justin's house is 8.82 miles from the museum.
