Question

How long does it take to drive 272 miles going 68mph

Answer 1

♥ It is going to take you 4 hours to drive 272 by going 68mph.
To do this you need to divide.
♥ 272/68=4

Answer 2

272mi/68mi/hr= 4 hr

Example:
Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario.

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds

Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2
