A man walks at the rate of 88 paces to the minute if the average length of his paces is 0.875m, find the time take to walk 2.31k

Nataly [62]

Answer:

30 minutes

Step-by-step explanation:

Walk rate = 88 paces/ minute

Average length of pace = 0.875 m

Time taken to walk 2.31 km ;

The distance in metres :

1000 m = 1 km

2.31 km = (1000 * 2.31) = 2310 m

Recall :

Time taken = distance / speed

Distance walked in a minute = 88 * 0.875 = 77 m

Time taken = 2310 / 77

Time taken = 30 minutes

A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.

11111nata11111 [884]

Answer:

56.7 mi/h

Step-by-step explanation:

The formula for average speed is:

Average Speed = $\frac{TotalDistance}{TotalTime}$

Thus we have:

Average Speed = $\frac{210+130}{3.5+2.5}\\=\frac{340}{6}\\=56.66$ mph

<em>Rounding to the nearest tenth, we have </em>

Average Speed = 56.7 mi/h

Answer:

$\frac{10}{9}\pi$ yards

Step-by-step explanation:

The circumference of this circle = 2πr

= 8π

We have to find the arc length of 50°, or 50/360 times the circumference of the circle(because there is 360° in a circle)

$\frac{50}{360} * 8\pi = \\\\\frac{400\pi}{360} =\\\\ \frac{10\pi}{9}$
