1) a salesperson drove for 50 km at an average speed of 40 km.the salesperson then drove a further 130 km at an average speed of 80km\h.a) what was the total distance travelled?b) what was the average speed for the whole journey?
If you drive at 167km/hr then you will be at your destination in 1 hour. If you drive at 80km/hr then it 167 / 80 = 2.0875 hours. Note that the speed above must be your average. So if you go a constant 80 in the city and 160 on the highway your average is 120. At that speed you will be there in 167 / 120 = 1.39 hours.
