Taylor drives 5 miles in 10 minutes. she stops at a light for 2 minutes. she then travels another 10 miles in 8 minutes. what was her average speed? answers - a. 45 mph b. 2 mph c. 0.9 mph d. 1.8 mph

A. 45 mph

Step-by-step explanation:

Notice that your units do not match the answers. Time in your problem is in minutes, but you need the answer in miles per HOUR. So first we convert,

1 hour = 60 minutes

So now we have our new given:

d₁ = 5 miles           d₂=0 miles (It was not moving)        d₃ = 10 miles

t₁ = 0.167 hrs           t₂ = 0.033 hrs                                   t₃ = 0.133 hrs

To get the average speed, you get the sum of distances and divided it by the sum of time:

So the answer is 45.05mph or 45 mph.
