Answer:
A. 3 hours 20 minutes
Step-by-step explanation:
The distance divided by the speed gives you the time.
(234 miles)/(70 mph) = 3.343 hours.
3.343 hours is decimal hours. We need hours and minutes.
1 hour = 60 minutes. We separate the whole hours from the decimal part of the hours, and we multiply the decimal part of the hours by 60 to find minutes.
3.343 hours =
= 3 hours + 0.343 hours
= 3 hours + 0.343 hours * 60 minutes/hour =
= 3 hours + 20.6 minutes
The closest answer is:
A. 3 hours 20 minutes
