Hatshy [7]

Answer:

8:07 am

Step-by-step explanation:

It takes 9 minutes to walk from his house to the bus station.  It then takes 92 minutes for the bus to travel from Birmingham to Coventry.  After arriving, he takes 12 minutes to reach his workplace.  This takes a total of 113 minutes.

9 + 92 + 12 = 113

Convert 113 minutes to hours and minutes.

113 - 60 = 53

1 hr and 53 min

He has to be at work by 10.  Subtract the time it takes to get to his work by the time he has to get there.

10 - 1 hr = 9

9 - 53 min = 8:07

The latest time he can leave is 8:07.

A blueprint for a house has a scale of 1:5 feet. The living room has a length of 2.5 inches and a width of 3 inches. What is the
stiks02 [169]

Answer:

Step-by-step explanation:

Set this up as a proportion, with inches on the top and feet on the bottom for our scale.  We will find the actual length first, then we'll find the width.

\frac{in}{ft}:\frac{1}{5}=\frac{2.5}{x}

Cross multiply to get that the actual length is 5(2.5) = 12.5 feet.  Now for the width:

\frac{in}{ft}:\frac{1}{5}=\frac{3}{x}

Cross multiply to get that the actual width is 5(3) = 15 feet.

If you want the area of the room, multiply the length times the width to get

A = 15(12.5)

A = 187.5 feet squared
