I will use 'hr' to mean hour and 'hrs' to mean hours.

<u>The airplane flies:</u>

200 miles per hr

400 miles per hr

600 miles per hr

Average speed = Total distance ÷ total time

= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr

Time = Distance ÷ Average speed

= 2000miles ÷ 400miles/hr = 5hrs

To find 42% of a number, we first convert the percent to a decimal: 42% = 42/100 = 0.42.

Next we multiply this by the number we're taking the percent of:

0.42(45603) = 19153.26.
