natita [175]

Mark and Don have to sell 11 and 59 marbles respectively.

<em><u>Explanation</u></em>

Lets assume, the number of marbles Mark has  is x

As, Don has 4 more than 5 times the number of marbles mark has, so the number of marbles Don has = 5x+ 4

Question says that the total number of marbles is 70. So, the equation will be...

x+(5x+4)= 70\\ \\ 6x+4= 70 \\ \\ 6x = 70-4\\ \\ 6x=66 \\ \\ x= \frac{66}{6}= 11

<em>So, the number of marbles Mark has = 11 </em>

<em>and the number of marbles Don has = (5*11)+4 = 55+4= 59</em>

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.
