To reach city A, you travel north for 2.00 hours covering 80.0 miles. You then turn due east and travel 45.0 minutes for another 20.0 miles to reach your destination. On the first leg of your trip (traveling north), what is your speed?
V = d/t = 80/2 = 40 mi/h.
To find the speed on the first leg of your trip, you need to divide the distance traveled by the time taken. In this case, the distance traveled is given as 80.0 miles and the time taken is given as 2.00 hours.
Speed = Distance / Time
Speed = 80.0 miles / 2.00 hours
Speed = 40.0 miles per hour
Therefore, the speed on the first leg of your trip (traveling north) is 40.0 miles per hour.
