Nuala drives to her grandma's. she drives at 20 miles per hour. the journey takes 50 miles. how long would the journey take if Nuala drove at 40 miles per hour?

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!
