Question

Aaron leaves one city at noon. He has to be at another city 186 km away at 3:00 P.M. The speed limit the entire way and 65 km/h. Can he arrive at the second city on time? Explain.

Answer 1

Yes, he can.

Explanation:

From noon to 3:00 pm, it's 3 hours.

If he drives on the speed limit with 65 km/h, andhas 186 kilometers to drive, he can make it on time.

3(65)=195 km.

195 is greater than 185, so he can make it on time.

Answer 2

If Aaron leaves one city at noon and has to be at another city at 3:00pm traveling at a rate of 65km/h, he will arrive to the second city on time.

Explanation:

Aaron has three hours (from noon to 3:00pm) to travel a distance of 186km. If he travels at a speed of 65km per hour, then we can multiply 65 km times the number of hours he has available, three, to get a total of 195km. So, Aaron can travel up to 195 km in the three hour period and since the city is only 186km away, he has time to make it there before the 3:00pm deadline.
