in 2.5 hours, Mr. Castelli drives a distance of 125 miles. He wants to know his average driving speed in the meters per minute. Complete the table to find Mr. Castelli’s average driving speed in meters per minute by using the units as a guide.

1,350 meters per min

Step-by-step explanation:

Given that Mr. Castelli covers 125 miles in 2.5 hours, the average speed = .

In miles per hr, average speed = .

Converting 50 miles/hr to km per hr:

If 1 miles = 1.62 km (unit conversion)

50 miles = 50*1.62 = 81 km/hr

Converting 81 km/hr to meters per hr:

1 km = 1,000 m (unit conversion)

81 km = 81*1,000 = 81,000 m/hr

Converting 81,000 m/hr to meters per minutes:

60 mins = 1 hr

Therefore, average speed =

Average driving speed of Mr Castelli in meters per minute = 1,350 meters per minute.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
