Problem 1 A motorist is cruising in their car at a constant speed of 25 m/s. Over the next 10 seconds, they accelerate at a constant rate until their speed is 30 m/s, then they stop accelerating and begin cruising at this new constant speed. How much distance do they cover while they're accelerating? Don't forget units!
