Question

What’s the velocity of a car traveling 144km in 90 minutes per hour

Answer 1

Answer:

96 mph

Explanation:

There are a couple of ways of doing this, but I will just use a proportion.

first off 1 hour = 60 minutes.

So 144/90 = x/60 will give me the answer per 60 minutes of miles per hour.

cross multiply to get  90x = 8640

divide by 90 to get 96 miles per 60 minutes or 96 mph.

Hope this helped.
