Question

directions: use this information to answer parts a and b.
in 2010, a maglev train in japan traveled 1.1 miles in 10 \\( \frac { 1 } { 2 } \\) seconds.
maglev trains use magnets to hover above the tracks. this helps them reach extraordinary speeds.
part a
find the speed of the train in miles per hour. round to the nearest tenth if necessary.
enter the correct answer in the box.
show hints
approximately \\( \square \\) mph

Explanation:

Step1: Convert seconds to hours

We know that \(1\) hour \( = 3600\) seconds. Given \(t=10.8\) seconds.

$$t=\frac{10.8}{3600}\text{ hours}$$

$$t = 0.003\text{ hours}$$

Step2: Use the speed formula \(v=\frac{d}{t}\)

Given \(d = 1.1\) miles and \(t=0.003\) hours.

$$v=\frac{1.1}{0.003}$$

$$v=\frac{1100}{3}\approx366.7$$

Answer:

\(366.7\)
