A car travels 24 miles in 45 minutes. What is its average speed?
- 18 mph.
- 32 mph.
- 36 mph.
Explanation from PART66Online
Average speed is distance divided by time. 45 minutes is 0.75 of an hour, so 24 miles divided by 0.75 hours equals 32 mph. The 18 mph answer wrongly divides by 45 directly instead of converting minutes to hours.

24 / 45 * 60 = 32

d=rt..solve for r...r=d/t r=rate,d=distance, t=time,
24/t=r t= 45/.60 =(.75)
24/(.75)=32mph
24/t=r t= 45/.60 =(.75)
24/(.75)=32mph
