Sagot :

Answer:

60÷12=0.2

0.2miles per minute

0.2x45=9miles

Answer:

9 miles

Step-by-step explanation:

The speed of 12 miles per hour means that for every hour, Clare is 12 miles further from the starting point.

1 hour ----- 12 miles

Since an hour is equivalent to 60 minutes,

60 mins ----- 12 miles

We can divide both sides by 60 to find the distance travelled per minute.

1 min ----- 12 ÷60= 0.2 miles

Multiply both sides by 45 to find the distance travelled in 45 minutes:

45 mins ----- 0.2(45)= 9 miles

Given that the starting position is at zero, Clare's position is at 9 miles after 45 minutes.
