Question

a car traveled 240 miles in 3 hours. at this rate, how many miles will the car travel in \\(\frac{1}{2}\\) hour?\
a 80 mi\
b 120 mi\
c 20 mi\
d 40 mi

Explanation:

Step1: Find the speed of the car

Speed is calculated by distance divided by time. The car travels 240 miles in 3 hours, so the speed \( v = \frac{240}{3} \) miles per hour.
\( v = 80 \) miles per hour.

Step2: Calculate distance for \( \frac{1}{2} \) hour

Distance is speed multiplied by time. So the distance \( d = v \times t \), where \( v = 80 \) and \( t = \frac{1}{2} \).
\( d = 80 \times \frac{1}{2} = 40 \) miles.

Answer:

D. 40 mi
