Problem 1

Emily went for a walk through the forest looking for a lemon tree.  Every 2 minutes she walked she had to stop and rest. She spotted a lemon tree and plucked off as many lemons she could. She carried on walking on and it took her an hour. How much times she had to stop and rest.

2 mins = Stop & Rest
1 hour divided by 2 = 30
If she had to stop every 2 minutes in a hour, along the way she stopped and rested 30 whole times

Problem 2

The adventure club went on a hike to see a waterfall. To get to the hike, the club members took 3 cars and 10 vans. There were 3 people in each car and 7 people in each van. How many people went on the hike? 

3 people x 3 cars = 9 people altogether in each car
7 people x 10 vans = 70 people altogether in each car
70 people + 9 people = 79 people altogether

Hope you have learnt a strategie on what I have solved > :)
