Question

A bicycle is traveling at 20 miles per hour. How many feet will it cover in 30 seconds? Round your answer to the nearest tenth of a foot.

Answer 1

Answer:

$Distance = 880ft$

Step-by-step explanation:

Given

$Speed = 20\frac{miles}{hour}$

$Time = 30\ seconds$

Required

Determine the distance

To answer this question, we make use of speed-distance relationship

$Speed = \frac{Distance}{Time}$

Make Distance the subject

$Distance = Speed * Time$

$Distance = 20 miles/hour * 30 seconds$

Convert seconds to hour

$Distance = 20 miles/hour * \frac{30}{3600} hour$

$Distance = 20 miles * \frac{30}{3600}$

$Distance = \frac{20 miles * 30}{3600}$

$Distance = \frac{600\ miles}{3600}$

$Distance = \frac{1}{6} miles$

Convert to foot

$Distance = \frac{1}{6} * 5280\ ft$

$Distance = \frac{1* 5280\ ft}{6}$

$Distance = \frac{5280\ ft}{6}$

$Distance = 880ft$
