Question #89eb8
1 Answer
Average speed = 61.4 km/hr.
In the first pre-nap/lunch leg, distance = ave speed x time = 98.5 x 2.35 = 231.5 km.
You nap/lunch for 87.65min = 87.65/60 = 1.46 hour.
You then drive another 122.8 km in 117.6/60 hours = 1.96 hrs.
Total distance = 231.5 + 122.8 = 354.3 km
Total time = 2.35 + 1.46 + 1.96 = 5.77 hour
Average speed = distance travelled/time taken = 354.3/5.77 = 61.4 km/hr
