Question

For the first 30 km, a bicyclist ride at a speed of v km/hr. For the remaining 17 km, he rode at a speed that was 2 km/hr faster than his original speed. What was the time t that he spent on the entire trip? Let t be the time (in hours) and find t if. V=18

find t in terms of V

Answer 1

The total distance that the bicyclist traveled was 30 + 17 = <<30+17=47>>47 km.

The speed at which the bicyclist traveled for the remaining 17 km was v + 2 = 18 + 2 = <<18+2=20>>20 km/hr.

The time that the bicyclist spent on the trip can be calculated by dividing the total distance traveled by the speed at which he traveled: t = 47 km / (20 km/hr) = <<47/(20)=2.35>>2.35 hours. Answer: {2.35}.
