Total distance to be driven = 135 miles The speed or velocity = 50 miles per hour Time taken to get there = unknown The formula of speed is: Speed = distance Time Rearrange the formula to find time as follows: Time = distance Speed Time = 135 / 50 = 2.7 hours To convert it into minutes = (2.7 × 60) = 162 minutes Or 2 hours and 45 minutes
