Question: A cyclist travels 150 km in 5 hours. If the cyclist had traveled at a speed of 30 km/h, the journey would have taken 3 hours more. What is the actual speed of the cyclist?
a) 25 km/h
b) 30 km/h
c) 35 km/h
d) 40 km/h
Solution:
Let the actual speed of the cyclist be x km/h.
Time taken at speed x:
150/x = 5
x = 150⁄5 =30 km/h
Hence, the actual speed of the cyclist is 30 km/h.
