Let's go to a store to buy some ice-cream. While walking, we can daydream, and, in a way, we can count this time as waiting time. We've declared a function to simulate that. Standing in the queue also qualifies as waiting time. We have another function for that.
In this task, call the walk function two times: first to go to the shop 352 meters away and then to go to a park 120 meters away, where you will eat the ice-cream. Between those calls, invoke the waitInQueue function.
For this task, assume that we're walking at a constant speed of 1 meter per second.
