Given parameters:
Recommend wheelchari ramp slope =
Rise of the new wheel chair ramp = 22 inches
Horizontal length = 24feet
Unknown:
Is the ramp steeper than the recommended = ?
Slope is the ratio of rise to the horizontal distance covered
Mathematically;
Slope =
Slope of the wheel chair ramp;
covert 24 feet to inches;
1 foot = 12 inches
24 feet = 24 x `12 = 288inches
Slope = =
The two slopes being compared are;
and
The steeper of the first one 1/12. It has a higher slope compared to the second one.
Given:
On the first day, she drove 650 miles in 10 hours.
On the second day, she got a later start and drove 540 miles in 8 hours.
To find:
Difference between average speed of second day and first day.
Solution:
We know that,
On the first day, she drove 650 miles in 10 hours. So, the average speed is
So, the average speed on first day is 65 miles per hour.
On the second day, she got a later start and drove 540 miles in 8 hours.
So, the average speed on second day is 67.5 miles per hour.
Difference between average speed is
Therefore, the average speed on the second day is 2.5 miles per hour is faster than first day.
