Answer:
a) 600 m
b) 1200 m
Explanation:
Given a distance-time graph of a motorcyclist's journey, you want to know the distance to the shop, and the distance traveled in the first 4 minutes.
Shop
The graph is the distance the motorcyclist is from home. Since the graph starts with the motorcyclist at the shop, and the starting value on the graph is distance from home = 600 m, we can conclude ...
the shop is 600 m from the motorcyclist's home.
Distance
The graph tells us the motorcyclist is 1800 m from home after traveling 4 minutes. Since the start of the journey was 600 m from home, the distance traveled in that 4 minutes is ...
1800 -600 = 1200 . . . . meters
The motorcyclist traveled 1200 meters in the first 4 minutes.
