Question

Use the formula d=r*t to solve this problem.
Marisol and Mee Young are taking Spain’s AVE train from Madrid to meet up with Marisol’s mother, who is in Seville, which is 336 miles away. If it took them 1.8 hours, how fast were they traveling?
a.
210ph
c.
605 mph
b.
350mph
d.
186 mph


Please select the best answer from the choices provided

A
B
C
D

Answer 1

To determine the speed at which Marisol and Mee Young were traveling, we can use the formula \( d = r \cdot t \), where \( d \) is distance, \( r \) is the rate (speed), and \( t \) is time.

In this case:

- \( d = 336 \) miles
- \( t = 1.8 \) hours

We need to solve for \( r \):

\[
r = \frac{d}{t}
\]

Substituting in the values:

\[
r = \frac{336 \text{ miles}}{1.8 \text{ hours}} \approx 186.67 \text{ mph}
\]

Rounding this to the nearest whole number gives us approximately 187 mph.

Comparing this to the options provided:

a. 210 mph
b. 350 mph
c. 605 mph
d. 186 mph

The closest and best answer is:

**D. 186 mph**
