Question

An airplane travels at a speed of 1.1 * 10^6 feet per hour. This plane logged 1.02 * 10^5 flight hours in its service life. Estimate how many feet the plane traveled throughout its service life. d = r * _________, d = ( ) () , d= ( 1* 1) (10^6 * _____), d = ___________ feet

Options:
A. 1.1 * 10^6
B. 1.02 * 10^5
C. 1.1 * 10^6 * 1.02 * 10^5
D. 1.1 * 10^5 * 1.02 * 10^6

Answer 1

To find the total distance an airplane has traveled throughout its service life, multiply its speed (1.1 × 10^6 feet per hour) by the total flight hours (1.02 × 10^5 hours), resulting in approximately 1.12 × 10^11 feet.

Step-by-step explanation:

The question concerns calculating the total distance that an airplane has traveled throughout its service life. To do this, we use the formula d = r × t, where d represents the distance, r is the rate or speed, and t is the time.

Given the speed of the airplane is 1.1 × 10^6 feet per hour and the total flight hours are 1.02 × 10^5 hours, we multiply these values to estimate the distance.

The calculation is as follows: d = (1.1 × 10^6) × (1.02 × 10^5). When multiplying numbers in scientific notation, we multiply the coefficients (1.1 × 1.02) and add the exponents for powers of ten (6 + 5), which gives us d = 1.1 × 10^6 × 1.02 × 10^5 feet. We then approximate the coefficients by multiplying 1.1 by 1.02 to get approximately 1.12. Thus, the total distance is approximately 1.12 × 10^11 feet.
