Question 1031801
1. The cyclist cycles at a steady speed of 5m/s. How many metres does the cyclist travel? How many seconds does it take the cyclist to complete the journey?

distance is 5 km
1 km = 1000 m
5 km = 5000 m

time taken by cyclist = d/r => 5000/5 - 1000 seconds

2. The car sets off 500 seconds after the cyclist and travels at a constant speed of 20/s. How many seconds does it take the far to complete the journey?

distance = 5000 m
rate = 20 m/s

time = 5000/20 = 100 seconds
