For the first 30 km, the bicyclist drove with a speed of v km/hr. For the remaining 17km he drove with a speed which was 2km/hr greater than his original speed. How much time did the bicyclist spend on the entire trip? Let T be the time (in hrs),
We can write a time equation using the above information. Time = dist/speed
T = +
:
find T if
a.) v=15
T = +
T = 2 + 1
T = 3 hrs
:
b.) v=18
T = +
T = 1.67 + .85
T = 2.252 hrs
