Question

problems 7 - 8: a plane flew at a constant speed between denver and chicago. it took the plane 1.5 hours to fly 915 miles. 7. complete the table. 8. how far would the plane fly in 10 hours at this speed? time (hr) distance (mi) 1 1.5 915 2 2.5 t

Explanation:

Step1: Calculate the speed of the plane

The speed formula is $v=\frac{d}{t}$, where $d = 915$ miles and $t=1.5$ hours. So $v=\frac{915}{1.5}=610$ miles per hour.

Step2: Complete the table for different times

• When $t = 1$ hour, using the formula $d=v\times t$, $d = 610\times1=610$ miles.
• When $t = 2$ hours, $d=610\times2 = 1220$ miles.
• When $t = 2.5$ hours, $d=610\times2.5=1525$ miles.
• When $t=t$ hours, $d = 610t$ miles.

Step3: Find the distance for 10 - hour flight

When $t = 10$ hours, $d=610\times10 = 6100$ miles.

Answer:

Time (hr)	Distance (mi)
1.5	915
2	1220
2.5	1525
t	610t

For question 8, the plane would fly 6100 miles in 10 hours.
