Answer:

It will take you 0.24 hour to ride to your grandparents’ home

It will take you 14 minutes to ride to your grandparents’ home

Explanation:

- Your average speed is 15 miles per hour

- The distance to grandmother home is 3.67 miles

- You need to know how long it will take you to do that

Distance = speed × time

Distance = 3.67 miles

Speed = 15 miles per hour

- Substitute these values in the rule above

∴ 3.67 = 15 × time

- Divide both sides by 15 to find the time

Time = 0.24 hour

* It will take you 0.24 hour to ride to your grandparents’ home

- You need to convert the time from hour to minutes

1 hour = 60 minutes

∵ Time = 0.24 hour

∴ Time = 0.24 × 60 = 14.4

Time ≅ 14 minutes

* It will take you 14 minutes to ride to your grandparents’ home
