Answer:
a)15:30
b)16 km
Step-by-step explanation:
Well, for "a", we notice that each box measures 30 minutes since there is a 4 box gap between 8:00 and 10:00. That's a 2-hour gap. 2 hours divided by 4 is 30 minutes. Meaning, that each box represents 30 minutes. So, Bethan arrives home at 0 km, which is at 15:30.
For "b", Siobhan goes to school when the graph is straight since school lasts a long time. That's at 8km. He goes there from 0 km, so it takes 8 km to get to school and 8 km to leave and go home. 8km + 8km is 16km, so it takes 16km.
