Question

at trace state park in mississippi, there is a 40 mile mountain bike trail. tommy rode 1/2 of the trail on saturday and 1/5 of the trail on sunday. he estimates that he rode more than 22 miles over the two days. is tommy's estimate reasonable?

Answer 1

Yes it is reasonable because he rode half of the trail on Saturday which was 20 miles, then 1/5 of the trail on Sunday which was 8 miles for a total of 28 miles. Thus he rode more then 22 miles over the two days and making his estimate plausible.
