Answer:
the total time walter spent practicing is 3 hours
Step-by-step explanation:
If a lion plot shows two Xs above each value of time, this means that 2 times he did a practice of that time
so to know the total time we would have to add up all the practices he did for each time
2 * 1/4 h + 2 * 1/2 h = 2 * 3/4 h =
2/4 h + 2/2 h + 6/4 h =
1/2 h + 1h + 1 1/2 h =
1/2 h + 1/2 h + 1h + 1h =
1h + 2h = 3h
the total time walter spent practicing is 3 hours
