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 = <<4*10=40>>40 times
In 5 days he does 2 sessions/day * 5 days = <<2*5=10>>10 sessions
He jumps 10 sessions * 40 times/session = <<10*40=400>>400 times in 5 days.
