Question

Mark estimated that the drive would take 3,000 minutes. It ended up taking 2 days. Did the drive take longer or shorter than he estimated? By how much (in hours)? Explain what you did to come to the answer.

Answer 1

The driver took shorter than estimated

It took shorter by 2 hours( 120

minutes)

Explanation:

Firstly we want to know if the drive took longer or shorter

By 2 days, the number of hours will be 2 * 24 = 48 hours ( recall 24 hours = 1 day

now , since 60 minutes give one hour, then 48 hours will me 60 * 48 = 2,880 hours

This is less than 3,000 hours

By how much?

Simply subtract the value of minutes in 48 hours from 3,000 = 3000-2880 = 120 minutes ( or two hours)
