Response:
55 mph. All options are incorrect.
Detailed explanation:
When speed changes inversely with the time taken, it can be expressed as v ∝ 1/t, where:
v represents speed,
t refers to the time taken.
This leads to;
v = k/t, with k being a constant of proportionality.
Given that Kris takes 5 hours traveling at 55 mph, we replace v with 55 mph and t with 5 hours in the equation to find k as follows:
55 = k/5
Cross-multiplying yields:
k = 55 * 5
k = 275
To determine the speed Martin needs to drive for 5 hours, we substitute k = 275 and t = 5 back into the original equation v = k/t as follows:
v = 275/5
v = 55 mph
Thus, we conclude that in order to travel for 5 hours, Martin must also drive at 55 mph.
The statue's height is 152 feet. To answer this question: The total height of the Statue of Liberty alongside its pedestal is 305 feet, which is 153 feet more than the statue’s height. You can derive the height h of the statue using the formula.
87.648Step-by-step explanation:Multiplying decimals can be challenging. However, by breaking the decimal multiplication into two distinct equations, it becomes simpler. Calculating 73.04 x 1.2 can be expressed as (73.04 x 1) + (73.04 x 0.2). You already know that 73.04 x 1 equals 73.04. Next, compute 73.04 x 0.2, equivalent to 73.04 divided by 5, resulting in 14.608. Finally, add the two results (73.04 + 14.608) to arrive at the final answer of 87.648.
It could be either C or D, but I think C is the correct choice.
