Chapter 2: Q.2.103 (page 57)

Short Answer

Expert verified

$41.57$ minutes

Step by step solution

01

introduction

Speed lets us know how quick or slow an article voyages and depicts the distance voyaged separated when taken to cover the distance. Speed is straightforwardly relative to Distance and contrarily corresponding to Time.

02

explanation

Given,

Speed = $55 m / m i n$

Distance = role="math" localid="1652000894624" $7500 f t = 7500 \times 3.28 = 2286.58 m$

Applying the formula,

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

$= \frac{2286.58}{55} = 41.57 \min$
