Give the step-by-step reasoning process and then the final answer. When Spencer jumps rope, he jumps 4 times per minute. He jumps for 10 minutes each session and does 2 sessions each day. How many jumps will Spencer do in 5 days?
In 1 session he jumps 4 times / minute * 10 minutes = 40 times. In 5 days he does 2 sessions / day * 5 days = 10 sessions. He jumps 10 sessions * 40 times / session = 400 times in 5 days.
The final answer: 400.
