Question

an elephant can travel at a constant speed of 25 miles per hour while a giraffe can travel at a constant speed of 16 miles in 1/2 hour which animal runs faster explain your reasoning

Answer 1

Elephant , because in one hour he travels 25 miles , while the giraffe in 1/2 hrs travels 16 miles, if you make it 1 hour for giraffe you would 16x2= 32 miles, so the elephant is faster

Answer 2

The giraffe runs faster

Explanation:

Given parameters

Let S1 represent the constant speed of the elephant

Let S2 represent the constant speed of the giraffe

S1 = 25 miles per hour

S2 = 16 miles per ½ hour

Required: Which animal runs faster.

To determine the animal that runs faster, we have to first make sure that the units of speed in both cases are the same.

For the elephant

S1 = 25 miles per hour.

For the giraffe,

S2 = 16 miles per ½ hour

We convert the constant speed of the giraffe to miles per hour

Since speed = distance ÷ time

S2 = 16 miles ÷ ½ hour

S2 = 16 miles * 2 per hours

S2 = 32 miles per hour

By comparison S2 is greater than S1, so the speed of the giraffe is greater than that of the elephant.

Hence, the giraffe runs faster.

This is so because the elephant can cover a distance of 25 miles in 1 hour. Given the same time, the giraffe will cover a distance of 32 miles.
