Mark is in training for a bicycle race. he needs to ride 50 kilometers a week as part of his training. he rode 18.23 kilometers on monday and 13.94 kilometers on wednesday. how much more does mark need to ride to complete his training for the week?

17.83

Step-by-step explanation: So first we want to add 18.23 and 13.94 because we want to find out how many kilometers he has already ridden for the week.

So, 18.23 + 13.94 = 32.17, so now that we have his total number of kilometers ridden for the week we need to take the end goal (50 kilometers) and subtract it from how many kilometers he has already done (32.17)

50 - 32.17 = 17.83 And that 17.83 is how many kilometers he needs to do to reach his goal for the week.
