Question

please help:John is traveling to a meeting that is 28 miles away. He needs to be there in 30 minutes. How fast does he need to go to make it to the meeting on time

Answer 1

Tham, distance, speed and time follow a basic rule:

DISTANCE = SPEED X TIME

Hence, with your question:
\[28 = speed\times\frac{30}{60}\]
\[speed = \frac{28\times60}{30} = 56\text{ }miles\text{ }per\text{ }hour\]
