Answer to Problem 2.1P

In two weeks there are 1.2×1012μs.

Explanation of Solution

In one week there are seven days and in one day there are twenty-four hours. In one hour there are sixty minutes and in one minute there are sixty seconds. In one second there are 106 microseconds.

Convert week to microseconds as follows:

2wk=(2wk)(7d1wk)(24h1d)(60min1h)(60s1min)(106μs1s)=1.2×1012μs.

Answer to Problem 2.1P

In 38.1 fts there are 41.8 kmh.

Explanation of Solution

In one day there are twenty-four hours and in one hour there are sixty minutes.

In one pound there are 0.453593 kg and in one feet there are 0.3048 m. Convert meter per day into kilogram to feet per minute into pound as follows:

554m4daykg=(554m4daykg)(1day24 h)(1h60min)(0.453593kg1lbm)(1ft4(0.3048 m)4)=20.2ft4minlbm.

Interpretation Introduction

Answer to Problem 2.1P

In 554m4daykg there are 20.2ft4minlbm.

Explanation of Solution

In one day there are twenty-four hours and in one hour there are sixty minutes.

In one pound there are 0.453593 kg and in one feet there are 0.3048 m. Convert meter per day into kilogram to feet per minute into pound as follows:

554m4daykg=(554m4daykg)(1day24 h)(1h60min)(0.453593kg1lbm)(1ft4(0.3048m)4)=20.2ft4minlbm.
