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.
Answer:
5740
Step-by-step explanation:
First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.
