Answer:
1 hour and 15 minutes
Step-by-step explanation:
Nuala drives 20 miles per hour, which makes the trip 2 hours and 30 minutes long. If Nuala drove at 40 miles per hour, the trip would take 1 hour and 15 minutes. Why? Because:
40 miles per hour
50 miles- 40 miles=10 miles (that makes 1 hour already)
so now we figure out how long it takes for 10 miles at the speed of 40 miles per hour.
10/40=1/4 and 1/4 of an hour or 60 minutes is 15 minutes.
Therefore, it would take Nuala 1 hour and 15 minutes if she drove 40 miles per hour.
Hope this helped!
