It takes Billy 15 minutes to complete 1/8 of a recipe.

Multiply 8 to both numbers

1/8 x 8 = 1

15 x 8 = 120

It takes Billy 120 minutes, or 2 hours, for him to complete the recipe.

hope this helps

It will take billy two hours to complete it because 15 minutes took up 1/8 of the time and 8 times 15 is 120. 120 minutes is 2 hours.

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.

Ulleksa [173]

Answer:

1,350 meters per min

Step-by-step explanation:

Given that Mr. Castelli covers 125 miles in 2.5 hours, the average speed = $\frac{distance}{time}$ .

In miles per hr, average speed = $\frac{125}{2.5} = 50 miles/hr$ .

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 = $\frac{81,000}{60} = 1,350 meters/min$

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